mARTin-B78 ce3ae79132 Fix streams permanently stuck holding the shared LLM lock (v1.14.2)

Confirmed in production: a streaming attribution/character-sheets
request held _attribution_llm_lock for 11+ minutes, well past its
configured timeout, silently rejecting every subsequent passage as
"Attribution engine busy" and falling back to the non-streaming view -
looking exactly like live-thinking had stopped working, when actually
one earlier request never finished.

Root cause: requests' timeout= on a stream=True call only covers the
connect + first byte, not gaps between later body reads. If the LLM
backend goes silent mid-stream (connection left open, no more chunks),
the blocked socket recv() inside iter_lines() can hang indefinitely.
Since that's a native blocking call, not a Python-level yield point,
neither an in-loop wall-clock check nor GeneratorExit from a
disconnected client can interrupt it - both only take effect at the
next bytecode boundary, which never arrives while blocked in the C
extension.

Added _watchdog_close: a daemon thread that force-closes the upstream
connection if the wrapped block hasn't finished within the configured
timeout. Closing the socket from another thread makes the blocked
recv() raise, unblocking the generator so its normal except/finally
cleanup (including releasing the lock) actually runs. Verified against
the live LLM backend post-restart: stream completes normally with
real token-by-token deltas, and the lock is confirmed free immediately
after.

Unreleased

[1.14.2] — 2026-07-06

Fixed

Live streaming ("watch the LLM think") could get permanently stuck, silently breaking casting/character-sheets for the rest of the session — confirmed in production: a stream held the shared attribution lock for 11+ minutes, causing every subsequent passage to be silently rejected as "busy" and fall back to the plain non-streaming view. This made it look like live-thinking had stopped working entirely, when actually one earlier passage never finished. Root cause: requests' timeout= on a stream=True call only guards the connection and first byte, not gaps between later body reads — if the LLM backend goes silent mid-stream, the blocked socket read can hang indefinitely, and since that's a native blocking call (not a Python-level yield point), neither a wall-clock check in the read loop nor the client disconnecting can interrupt it. Added a watchdog thread that force-closes the connection if a stream runs past its configured timeout, guaranteeing the shared lock always releases on schedule regardless of backend behavior.

[1.14.1] — 2026-07-06

Fixed

"Reading PDF… page N" indicator drifted toward the bottom of the screen on long documents — it used position: sticky with a top: 40vh offset, whose containing block grew with every page appended during parsing, so the pill drifted downward instead of staying a fixed distance from the actual visible top of the viewport. Switched to position: fixed, anchored near the top regardless of document length.

[1.14.0] — 2026-07-06

Added

Watch Character Sheets fill out live — the "Character sheets" progress dialog now has a "Live output" pane that streams the LLM's raw answer as it's written for the passage currently being processed, the same live-streaming approach already used for casting. Backed by a new /api/character-sheets/stream endpoint (sharing prompt-building and parsing with the existing blocking one), with automatic fallback to the blocking endpoint if the model/backend doesn't support streaming.

[1.13.10] — 2026-07-06

Fixed

"Cast as audiobook" icon was invisible — a leftover rule colored its icon accent-blue from when the button was still the plain/secondary style; after making it the primary blue button, that same blue-on-blue rendered the icon invisible against the button's own background.

[1.13.9] — 2026-07-06

Changed

"Recast selected" no longer re-reads the whole book — it now only sends the passages that actually mention the picked character(s) (matched against their name and known aliases), plus one chunk of surrounding context on either side for pronoun resolution, falling back to the full book only if nothing matched at all. Recasting one character out of dozens now takes a handful of passages instead of the whole thing.

[1.13.8] — 2026-07-06

Changed

Read Aloud toolbar decluttered — removed the standalone "Character sheets" button (redundant with "Cast Characters" already in the Casting flow) and made "Cast as audiobook" the primary blue action, moved to the end of the toolbar as the clear next step.

[1.13.7] — 2026-07-06

Fixed

"Recast selected" showed every character as queued, not just the ones picked — the progress dialog looked exactly like a full recast because it was passed the entire roster as the target list; the selection only actually took effect at the final save step. Now only the picked character(s) go in as the target roster, so the dialog accurately shows just those as queued.
"Recast options" dropdown routinely opened off-screen — its anchor button sits in the bottom action bar, so the menu opening downward (the default) was often pushed past the viewport edge, barely visible. It now opens upward when there isn't enough room below, and is styled more prominently.

[1.13.6] — 2026-07-06

Fixed

Large empty gap in Read Aloud's tuning panel — the backend hint box sat beside the 4 tuning rows (Speed/Seed/Temperature/Native speed) and was forced to stretch to their combined height regardless of how short its own text was, leaving a big empty area below a 1-3 line hint. Moved it to full width below the rows, sized to its own content.

[1.13.5] — 2026-07-06

Added

Search + sort in the Casting sidebar ("Characters found") — filter by name and sort by line count or alphabetically, matching the same controls added to the Library's character list.

Fixed

Merging characters could freeze the page long enough to trigger the browser's "Page Unresponsive" dialog — the merge itself is a fast array loop, but redrawing the whole feed afterward (thousands of DOM rows, each running the highlight regex pass) was one long synchronous block. A spinner overlay alone couldn't fix this — it would freeze right along with everything else in the same JS turn. The redraw is now chunked across animation frames with a real, moving progress bar, so the browser stays responsive and the merge no longer looks like a crash on a large book.

[1.13.4] — 2026-07-06

Added

Merge two roster entries from the "also known as" popup — when the LLM splits one character into two roster entries (e.g. "Darag" and "Schmied" for the same person), the alias popup now lists other already-recognized characters as pick-to-merge options, not just a free-text field. Picking one actually reassigns every one of its segments to the character you opened the popup from (not just a linked library alias that leaves the live cast still showing both), with full undo support.

Fixed

Character table view still misaligned after the earlier fix — display:flex directly on a <td> (Stimme, Tags columns) broke its table-cell layout participation entirely in Chromium, rendering the cell stacked at the previous column's position regardless of table-layout mode. Moved the flex layout to inner wrapper <div>s and switched the table to table-layout:fixed with an explicit <colgroup> for good measure.

[1.13.3] — 2026-07-06

Fixed

Dragging a short quoted line ("»Henker«.") to split it opened the Assign-to-character popup instead — any selection under 40 characters was treated as "assign this text as a character name," even when it was clearly a short quoted line (guillemets/quotes are never part of a name). Selections starting with a quote mark now fall through to the "Split text to Unknown Speaker" button instead of being hijacked into the assign popup.

[1.13.2] — 2026-07-06

Fixed

Character table view rendered as stacked blocks, not a table — table rows reused the .lib-char-card class (for its click/voice/export wiring) whose display:flex;flex-direction:column turned every <tr> into a flex column, stacking its cells vertically instead of laying them out side by side. Reset to display:table-row and stripped the card-specific chrome (background, border, shadow) that leaked in with it.

Changed

One Generate button per prompt box instead of a single "Generate" that always regenerated all four (Voice Design, Character Image, SillyTavern, Concept Art) at once. The server endpoint now accepts a fields filter and runs one independent LLM call per requested field — clicking one button no longer burns tokens on the other three, and each call's smaller JSON further reduces truncation risk.
Sort dropdown for the character list (Library → Characters/Cast) — Role/Alphabet/Number of lines/Gender/Voice assigned, persisted like the Cards/Table toggle.

[1.13.1] — 2026-07-06

Added

"View Characters" + recast options once a book's already cast — Read Aloud's Casting view no longer offers a single blind "Cast Characters" button once this book already has saved characters. It becomes a split button: View Characters jumps straight to the Library's character overview, and the dropdown caret offers Recast all (previous behavior) or Recast selected…, which opens a checkbox picker of the existing cast and only refreshes the ones you check — everyone else's saved sheet is left untouched. (Extraction still re-scans the whole book either way, since any page could mention any character; "selected" just controls what gets saved afterward, not what gets read.)

[1.13.0] — 2026-07-06

Changed

Script Rehearser's Stage character list is now a sidebar, matching Read Aloud's Casting sidebar look exactly (same .ab-cv-side/.ab-char-item styling: colored dot avatar, name, line count) instead of the old horizontal avatar strip above the transport bar. It sits alongside the script page, collapses to just the avatar dots via the same chevron control, and clicking a character scrolls the script to their first line.

[1.12.99] — 2026-07-05

Fixed

"Design all" (Script Rehearser bulk voice design) silently did nothing — confirmed via server logs: /api/analyze-characters succeeded every time, but /api/voice-design was never once called. Root cause: rehState.cast[sp].voice was accessed unguarded right after the (multi-second, for a large cast) analyze-characters request resolved; any cast-entry change during that window threw a TypeError with nothing to catch it, silently killing the whole run with no toast and no further requests. Guarded the access and wrapped the rest of the flow in a try/catch/finally so any future failure surfaces as a toast and always re-enables the button instead of leaving it stuck with no feedback.

[1.12.98] — 2026-07-05

Added

Character table view in Library → Characters/Cast (toggle next to "Import from SillyTavern") — one row per character with avatar, name, sex, line count, assigned voice's language, moral alignment bar, voice, tags, and check/cross indicators for whether the SillyTavern, TTS voice-design, and image prompts have been generated. Persists your choice between Cards/Table.
Bulk voice auto-assign — a checkbox on every character card/row plus an "Auto-assign selected" button in each production's header, so you can voice-cast a batch of characters in one click instead of one at a time. Runs sequentially (not in parallel) so each assignment sees what the previous one just picked and doesn't hand out the same voice twice.
Character tags are now visible on cards — every character is auto-tagged with the book it was extracted from (already happened silently); the cards just weren't showing it. Useful for spotting the same character recurring across different books.
Jump-to-source links on detail fields — Backstory, Motivation, Relationships, etc. now show small numbered links next to the label when the sheet has a citation for that field; clicking one scrolls straight to the exact page + quote in "Quellen im Text" instead of making you search the full source list.
Gender is now an extracted character-sheet field (male/female/nonbinary) — it existed in the UI already but the LLM was never actually asked for it, so every character silently showed the same default icon.
Line-count tracking (best-effort) — casting from Read Aloud or Script Rehearsal now tallies each character's dialogue-line count into their sheet when it's available in memory, feeding the new table view's "Zeilen" column.

Fixed

SillyTavern & Concept Art prompts still silently failed to generate even after the earlier max_tokens increase — they're the last two fields in a four-field JSON object, so any truncation always cost the same two fields regardless of the ceiling. Split into two independent LLM calls (Voice Design + Image / SillyTavern + Concept Art), run concurrently, each with its own full token budget — a squeeze in one pair can no longer cost the other pair anything.

[1.12.97] — 2026-07-05

Fixed

German umlauts mojibake'd during live casting ("Häfen" → "HÃ¤fen") — the streaming attribution endpoint decoded the LLM's SSE response with requests' guessed encoding, which falls back to Latin-1 when the upstream doesn't declare a charset. Forced UTF-8 explicitly.
"LLM Thinking" pane duplicated the passage text for models that ignore the reasoning-preamble instruction and stream straight into JSON. It now only shows genuine <think>...</think> content when present, and otherwise labels the pane honestly ("Live Output (raw — no reasoning exposed)") instead of passing off raw JSON as thinking.
A−/A+ font-size buttons had no visible effect — .ab-cv-row had a hardcoded font-size: 13.5px that always overrode the CSS variable the buttons set on an ancestor. Now scales with it.
Typing a new name + Enter in the "Assign to" popup silently did nothing (after the first cast/recast run in a session) — the popup is a page-lifetime singleton, but its input's Enter/typing handlers closed over whichever run's assignName existed the first time the popup was created. Every later run's popup opens now repoint those handlers at the current run.
Click-and-drag assign stopped working after the first run, for the same reason as above (drag pre-fills the popup, then confirming it hit the same stale closure).
"Split text to Unknown Speaker" split at the wrong spot when the selected phrase (or a whitespace-trimmed variant) occurred earlier in the same paragraph — it searched for the text with indexOf instead of using the actual selection position. Now computes the exact DOM-range character offset, so it always splits where you dragged, regardless of repeated text elsewhere in the passage.

[1.12.96] — 2026-07-05

Fixed

Server crashes with "RuntimeError: No response returned" — the static-asset caching middleware used @app.middleware("http") (Starlette's BaseHTTPMiddleware), which has a known bug: when a client disconnects mid-StreamingResponse (e.g. the new live-attribution SSE stream hitting its idle timeout), its internal task group races the disconnect and raises this error. Rewritten as plain ASGI middleware that only touches response headers via the raw send callable — it never wraps the response the way call_next() does, so the race is gone entirely.
Casting timeouts/405s during long runs — the streaming attribution endpoint used its own lock, separate from the blocking endpoint's. That meant a stream request and its own blocking fallback could both fire into the LLM's single processing slot at once — exactly the "ghost request" pile-up the original lock existed to prevent. Both endpoints now share one lock. Stream failures are also logged server-side now (silent before).

Changed

The "LLM Thinking…" pane now shows real reasoning, not the JSON answer echoed back. The attribution prompt asks for a brief <think>...</think> rationale before the JSON when streaming; the client shows only that block and stops once it closes, instead of dumping the raw in-progress JSON (which mostly just reproduces the passage text).

[1.12.95] — 2026-07-05

Added

Watch the LLM think, live — the "LLM Reading…" card now splits into two panes the moment the model starts responding: its raw output stream (reasoning + the answer JSON as it's written) on the left, the passage it's reading on the right. Backed by a new streaming endpoint (/api/attribute-dialogue/stream, SSE) that forwards both reasoning_content (thinking models) and content deltas; the prompt-building and answer-parsing are shared with the blocking endpoint so the two can never drift. Any stream failure falls back to the blocking endpoint automatically — with an inactivity timeout (reset on every received chunk) instead of an overall one, since a slow model legitimately takes minutes per passage but long silence means the stream died. Works in the main cast, Recast unknown, and 2nd Quality Run.

Fixed

Resolver invented characters from scenery words — the deterministic colon-rule's fallback accepted any "der/die + capitalized noun", turning "auf dem Platz", "die Gesichter", "eine Kleinigkeit" into speakers PLATZ/GESICHTER/KLEINIGKEIT. The fallback is now a closed whitelist of person/role nouns, plus a clause-subject pattern ("Marcian unterdrückte seinen Ärger und sagte:" → Marcian).
More Unknowns resolved, safely — two new deterministic rules: the impersonal post-quote formula ("ertönte es plötzlich über ihm. Karyla hatte…" → Karyla), and strict two-person alternation (both nearest preceding dialogue lines named and different → the one who didn't just speak), guarded to never fire across page boundaries, beyond a short window, or when the preceding narration ends with ":" (that colon introduces someone the other rules couldn't name — alternation would be a guess, not a deduction). All screenshot failure cases verified against the exact book sentences.

[1.12.94] — 2026-07-04

Fixed

2nd Quality Run / Recast unknown appeared to wipe all named characters — the sidebar roster was rebuilt only from the lines being checked, so it collapsed to "Unknown " as if the whole cast was lost. The cast itself was never touched (named lines are never targets, and a run that would increase Unknowns already rolls back completely) — but the display now seeds from the full cast and stays correct as the run progresses.
"API Error while checking Unknown line:" with no reason — statusText is empty on HTTP/2, so error notes ended blank; they now fall back to the HTTP status code.

Changed

Quality runs apply the grammar rules first — the deterministic resolver (colon rule, post-quote inquit, "who had spoken") now runs before any LLM call in Recast unknown / 2nd Quality Run, resolving the mechanical cases instantly and shrinking the LLM's queue.

[1.12.93] — 2026-07-04

Added

Deterministic Unknown-resolution pass during casting — measured on a full book, the LLM left ~44% of dialogue "Unknown" even with all deduction rules in its prompt, so the two most mechanical rules are now applied in code after each passage, where they can't be ignored: the colon rule (narration ending in ":" names the next quote's speaker — with a non-agent-noun stoplist so "rief in die Runde:" resolves to the Ork, not "Runde"), post-quote inquits ("fragte Uriens leise." after a quote), and the "Der Krieger, der gesprochen hatte" pattern. Only fills segments the LLM left Unknown; never overrides an actual attribution. Verified against the exact failure cases from the reported screenshots.

[1.12.92] — 2026-07-04

Fixed

Deduction rules never reached the LLM when a custom prompt was saved — the saved casting prompt turned out to be the 2nd-Quality-Run verification prompt (pasted into the Prompt panel at some point), which tells the model it's reviewing an existing segmentation instead of doing first-pass attribution, and contains none of the speaker-deduction rules; the client-side prompt auto-upgrade found no anchor text in it and silently skipped. Two fixes: the server now appends the deduction rules to any prompt that lacks them (attribution quality no longer depends on prompt history), and the misapplied saved prompt was reset to the shipped default (backed up to config/audiobook_prompt.backup.txt).
Every "die"/"der" underlined as a character name — a descriptive alias like "Die, die den Vampir verließ" gets comma-split into tokens, and the bare article "Die" became an alias that matched every article in the book. Bare articles/pronouns are now filtered out of alias token lists.
Raw style="…" HTML leaking into casting text — name-highlighting replaced name-by-name over HTML that already contained the injected highlight spans, so a shorter alias could match inside a longer name's data-name attribute and corrupt the markup. All names are now matched in a single combined pass that never re-scans its own output.

Added

Chapter headings render as headings in the casting feed — short standalone narration that reads like a title ("Prolog", "1. Kapitel", an OCR'd headline band) is now bold, larger, and centered on the paper page.
Font-size controls in the casting toolbar — A−/A+ buttons scale the paper pages' text; the size is shared with the Script Rehearser Stage (same persisted scale), so one reading size applies across both screens.

[1.12.91] — 2026-07-04

Fixed

No way back from Cast Characters to the casting script — the Characters/Cast view's production bar now has a "Casting" button that returns to the active casting session (via the reader's cast-restore), the pipeline stepper now also renders on the Library section so prev/next navigation works from there too, and the stepper's "Cast Characters" stop now navigates to the Characters/Cast view instead of kicking off sheet generation as a side effect of clicking a navigation element.
Two of the four generation prompts silently came back empty — the LLM's answer was truncated by a too-small output budget (1600 tokens for four prompts, one of them multi-section), the JSON parse failed, and the UI showed success with two empty boxes. The budget is now 4096 tokens, a cut-off answer is salvaged for the fields that did complete, an all-empty response is a loud server error instead of a silent success, and a partial result names exactly which prompts are missing so you know to hit Generate again.

Changed

"Reading PDF… page N / M" progress pill enlarged and vertically centered in the document pane (was a small pill pinned to the top edge), so long extractions have a clearly visible "still working" signal.

[1.12.90] — 2026-07-04

Fixed

Page freezes ("Page Unresponsive") after opening a book / the casting feed — the recent "click any word to assign" feature wrapped every single word of every casting segment in its own <span> with hover styles; at book scale (~1,500 segments) that meant ~100,000 extra DOM nodes rebuilt synchronously on every feed redraw, freezing the tab. The spans are gone: the word under the cursor is now found via the browser's native caret-position API (caretRangeFromPoint) and highlighted with a single reused overlay element — same click/hover/drag-to-assign behaviour, zero extra DOM.
Burst of identical export downloads — clicks queued up while the page was frozen could all fire at once on the export button when the tab unblocked, spawning one download + save-dialog per queued click. The export now ignores re-triggers for 2 seconds (and the freeze itself is fixed above).

Changed

"Export cast .md" is now "Export cast .zip" — one zip bundle containing the cast as a readable Markdown script plus a Markdown sheet per character of the book (identity, appearance, personality, story, abilities, and the generation prompts), instead of a single cast file and no character sheets at all.

Added

Generation Prompts on every character sheet — a new section in the Character Library detail view with four fold-out, copy-ready prompt boxes: Voice Design (Qwen3 TTS), Character Image (profile portrait), SillyTavern character card, and Concept Art (turnaround/model sheet). A "Generate" button fills all four in one LLM call over the character's complete profile — the previous behaviour generated voice/image prompts passage-by-passage during sheet extraction, where the model only ever saw a fraction of the character. The boxes are editable in place (autosaved like every other sheet field) and the results are included in the cast .zip export.

[1.12.89] — 2026-07-04

Added

Quick "add alias" shortcut in the Casting sidebar — hovering a character in the "Characters found" list now reveals a small tag icon; clicking it opens a tiny popup to add an "also known as" name (e.g. "Garthai" for "Sharraz Garthai") without leaving the casting screen. Writes through the same clUpsert the rest of the app uses, so the alias is immediately shared with Rehearser/Character sheets and starts getting recognized/underlined in the casting text right away.

[1.12.88] — 2026-07-04

Added

Pipeline stepper prev/next navigation — small chevron buttons flank the stepper to step to the nearest reachable stage in either direction, instead of only being able to jump directly to a specific stop.
Footer engine chips are now clickable fly-up menus — click the LLM/STT/TTS chip in the footer status bar to quickly switch the active model (LLM: fetches the live model list for the current endpoint) or backend (STT/TTS: applies your pick to every matching picker across the app) without hunting through Settings or each screen's own dropdown.
Click or drag a name inside the casting text to assign it — every word in the narration/dialogue text is now hoverable and clickable, not just the speaker label. Clicking a word opens the assign popup pre-filled with it; dragging across several words (for a multi-word name the roster doesn't know yet, e.g. "Sharraz Garthai") pre-fills the full phrase; double-clicking an already-known name/alias assigns it immediately with no popup. Built on the existing text-selection infrastructure (the "select text to split this segment" feature) rather than a separate mechanism, so the two don't fight over the same drag.

[1.12.87] — 2026-07-04

Added

Real paragraph/chapter-break detection for PDFs — extraction now flags where a new paragraph starts (readerMarkParagraphBreaks) by comparing each line's vertical gap against the page's typical line spacing; a heading/image band followed by a large gap before body text is caught by the same check. The break is preserved as a real blank line all the way through sentence-building, unit-grouping, audiobookScopeText, and splitTextIntoChunks — previously every paragraph and chapter heading in a book was silently joined into one run-on blob before the casting LLM ever saw the text. The attribution prompts (default, saved-prompt auto-upgrade, "2nd Quality Run", and the server-side fallback) now explain how to read the blank lines, including treating a short standalone line before one as a chapter heading rather than dialogue.

Fixed

Merging two casting segments dropped their page number — _abMergedSegment built a fresh segment object and never carried over .page from either side, so a merged row would silently render as if it belonged to whatever page card came before it. It now anchors to the earlier segment's page.
Export cast .md was a JSON dump with a Markdown label — the exported file's entire content was one big fenced json code block; it's now an actual readable script (plain paragraphs for narration, **SPEAKER** (emotion): "line" for dialogue, grouped under page headings), on both the server export route and the client-side fallback used when a book has no server id yet.

Changed

"Edit in Rehearser" renamed to "Edit Characters" — the button always lands on Rehearser's Cast/voice-assignment screen, not general script editing, so the label now says what it does.
Casting text no longer edits via double-click — only the pencil icon opens a row for editing now, so selecting/dragging across a name to assign a character (a much more common action) can't accidentally drop you into edit mode instead.

[1.12.86] — 2026-07-04

Changed

Speaker attribution taught the deduction rules it kept missing — the casting prompt's attribution section grew from 6 to 10 rules covering exactly the patterns behind most false "Unknown"/"Narrator" assignments: the colon rule (an inquit sentence ending in ":" names the next quote's speaker), post-quote attribution across the segment boundary (»Quote« — "ertönte es über ihm. Karyla hatte …" → Karyla spoke), mandatory pronoun resolution to the last-named person of matching gender, the addressee rule ("X wandte sich an Y" → X speaks next, Y answers), strict two-person ping-pong carried through tag-less exchanges (where 'Unknown' is almost never right), and role designations ('Ork', 'Nachbar', 'Der Fremde') as valid speakers instead of 'Unknown'. Saved custom prompts are upgraded in place via the existing prompt-migration mechanism, and the "2nd Quality Run" verification prompt gets the same deduction toolkit.
Book language now auto-detected for casting — the attribution request's language hint previously came only from a manual dropdown that usually sat empty; it now falls back to detecting the language from the book text itself, so German books always get the German grammar/wording instruction without any manual step.

[1.12.85] — 2026-07-03

Performance

Heading OCR renders only the top band, not the whole page — the OCR pass rasterized every full page at 2.5× scale (~6M pixels for A4) and then cropped ~10% of it; the canvas is now sized to the band itself so the remaining ~90% is never rendered or allocated. Also: the Tesseract worker (tens of MB of WASM/language data) is now terminated after extraction instead of living for the whole session, and the top-gap scan no longer allocates a throwaway array per page.
Casting feed name-underlining no longer rebuilds its name index per segment — the list of character names/aliases and their compiled regexes was recomputed for every rendered segment (O(segments × records) over a full book); it's now cached and invalidated only when the roster or character records actually change. The dialogue-splitting fallback also compiled a constant regex once per sentence-ending character; hoisted to a module constant.
Old casting drafts migrate their page numbers once at load — drafts saved before segments carried a .page field were re-deriving page boundaries via text search on every feed redraw; they're now stamped once when the draft is applied, and the renderer is single-path.

Changed

[hidden] now always hides, globally — one root rule ([hidden]{display:none!important}) replaces the per-component patches this bug class kept requiring (.ab-char-bar, .wf-stepper, .reader-extract-banner, .ab-castpanel-inline, and ~20 others individually). New components can no longer reintroduce the empty-box-while-hidden bug.
Removed the racy cast-panel view override — navigating to Read Aloud restored an active casting session via a deferred setTimeout that overrode whatever view the caller had just chosen, which needed a global suppress flag (_readerSuppressCastRestore) set from two unrelated places to defeat. The restore is now synchronous and respects an explicit view request, so the flag is gone and callers simply win by calling showReaderView() after navTo(). This also fixes the sidebar "Reader" item landing in the casting view instead of the reader while a cast was active.
Cards can declare their collapse default in markup — data-collapse-default="closed" on a card is now read by the generic collapse mechanism, replacing reader.js writing another module's localStorage key derived from the card's heading text (which would have silently broken on any heading rename).
Deduplicated helpers — casting's segment-join, colour (hue/hex/normalize), and alias-splitting logic now delegate to the canonical implementations (audiobookJoinSegmentText, clNormalizeColor/clHslToHex/clNameHue, clSplitIdentityTokens) instead of maintaining byte-identical private copies; the status bar's LLM endpoint resolution is now a single shared statusLlmTarget() instead of two identical inline copies.
Removed dead state — readerState.pdfParsing/pdfParsedPages/pdfParseTotal (never set, only reset — including a toast suffix that could never appear) and the write-only readerState.textExtracted flag.

Fixed

Pipeline stepper never hid on a fresh session — the "show only when a document is loaded" guard still checked for the old 'pdf' step key after the PDF/Text merge into "Source", so the always-available Source stop kept the strip permanently visible.

[1.12.84] — 2026-07-03

Fixed

Clicking "PDF" or "Text" in the pipeline stepper did nothing — navTo('s-reader') auto-restores an active casting panel a tick later via a deferred setTimeout (nav.js), which silently undid the stepper's own showReaderView('main') call right after it ran. Now sets the existing _readerSuppressCastRestore flag (already used by the Library's "open a fresh book" flow for the same reason) before navigating.

Changed

Merged the "PDF" and "Text" stepper stops into one "Source" — both stops led to the exact same Reader screen, so distinguishing them added a step without adding a real destination. Named "Source" to match the label already used on the Reader's import card. The stepper is now 6 stops instead of 7.

[1.12.83] — 2026-07-03

Fixed

Casting feed merge/split/edit got slower as the merge work landed — the new per-row inline-edit feature attached 2 extra event listeners to every segment row on every redraw, and merge/split rebuild the entire feed from scratch; for a 1000+ segment book that's thousands of extra listener attachments on every single merge/split. Moved editing to the same event-delegation pattern already used for merging and speaker assignment (one listener on the feed container, not one per row) — row creation is back to just building HTML.
Reader's playback transport bar stayed visible with nothing loaded — readerResetDoc() hid the synth bar and the zoom/search toolbar but never hid the play/pause/skip transport bar, so a reset or fresh session showed "0 / 0" controls with no document — one of several boxes making the empty-state Reader screen feel cluttered.

Changed

Pipeline stepper made prominent, like a guided tour — bigger numbered circles, a current-step highlight ring, and completed steps now show a checkmark and stay tinted instead of all steps looking equally flat.
"Voice & synthesis settings" now collapsed by default — it's secondary until you actually have a document loaded; this was the first thing filling the empty-state screen with a large expanded box before you'd done anything.
.ab-castpanel-inline background set to var(--panel) explicitly, per spec.

[1.12.82] — 2026-07-03

Fixed

Duplicate "opening" notifications when reopening a saved book — a toast ("Opening book…") and the "Reading PDF… page N / total" progress pill appeared at almost the same instant and visibly overlapped on screen. Removed the toast — the progress pill already says the same thing with more detail (live page count) and stays up for the whole load instead of auto-dismissing.

[1.12.81] — 2026-07-03

Fixed

Casting toolbar icons overlapping at narrower panel widths — .ab-cv-topbar (character-selection bar + undo/redo + page navigation) never wrapped, so when all three were visible at once at a moderate panel width, its fixed-width buttons got crammed together instead of flowing to a second row. Added flex-wrap: wrap.

[1.12.80] — 2026-07-03

Added

First slice of the Read Aloud / Rehearser merge — three pieces of the planned unified screen land in Casting audiobook now: (1) the "paper" page look — pages are now literal white/off-white sheets (Courier New, matching Script Rehearser's Stage exactly) inside the Casting border/shadow "stacked card" treatment, instead of a plain surface-coloured box; (2) the character sidebar is now collapsible to just avatar dots via a new chevron toggle, for more room when you don't need the full list; (3) every line in the casting feed can now be edited inline (pencil icon or double-click, Ctrl+Enter to save, Esc to cancel) — previously only speaker reassignment and segment merging were possible, not correcting the text itself. More pieces of the merge (shared page navigation, folding Script Rehearser's Stage into this same view) are in progress.

[1.12.79] — 2026-07-03

Fixed

Theater Play library cards silently failed to open at all — the real cause, on top of the missing navigation fixed in 1.12.78: opening a saved rehearsal (from Library → Theater Plays, and from Rehearser's own Library tab's open/export buttons) called rehDbOpen()/REH_STORE, a raw-IndexedDB API left over from before the app migrated rehearsals to server-backed SQLite. Neither exists anymore, so every click threw a ReferenceError caught silently by the surrounding try/catch — loadRecord() was never even reached, which is also why the 1.12.78 navigation fix alone didn't fully solve it. All three spots now use rehDbGetById(), the current API.

[1.12.78] — 2026-07-03

Fixed

Theater Play library cards did nothing when clicked — opening a saved rehearsal from Library → Theater Plays called loadRecord(), which loads the script/cast and switches to the Cast phase, but never navigated to the Rehearser section itself. Since you're sitting on the Library section when you click a card, the phase switch happened inside #s-rehearser while that whole section stayed hidden — so nothing visibly changed. loadRecord() now navigates to Script Rehearser first.

[1.12.77] — 2026-07-03

Fixed

Excessive "Unknown" speakers in Casting audiobook — the attribution LLM's output budget had been tightened to roughly half its previous size (len(text)*0.45+512 vs. the old len(text)+1000, both capped). Narration-heavy passages fit fine, but dialogue-dense scenes need far more output than input — every quoted line becomes a full JSON object — so the tighter cap truncated the response mid-JSON on exchange-heavy passages. The truncation-repair only salvages a cut that lands right after a complete segment, so most failures degraded the whole chunk to naive quote-splitting, which has no way to attribute a speaker and labels everything "Unknown". Restored the more generous budget.

[1.12.76] — 2026-07-03

Fixed

Bulk "Set tag" wiped a voice's existing tags — applying a tag to multiple selected voices overwrote each voice's tag field outright instead of adding to it, so a voice tagged "Privat, Sillytavern" lost both tags the moment you bulk-tagged it with something new. It now merges the typed tag(s) into each voice's existing tag list instead of replacing it.

[1.12.75] — 2026-07-03

Fixed

Casting audiobook panel grew to fit its content instead of the browser window — the inline casting view (.ab-castpanel-inline) had no bounded height, so .ab-cv-body's flex:1 had nothing to divide up; the feed grew with every passage cast, pushing the action bar ("Continue casting" / "Edit in Rehearser" / ...) further down the page and forcing a full-page scroll to reach it. It's now bounded to the viewport like the floating casting popup already was, so the feed scrolls internally and the header/action bar stay in view.

[1.12.74] — 2026-07-03

Fixed

Empty bar showing above Rehearser's Library tab (and potentially the Reader's "Extract Text" prompt) — the new .wf-stepper and .reader-extract-banner rules set display: flex unconditionally, which beats the browser's default [hidden] { display: none } rule at equal specificity — the same bug class fixed previously for .ab-char-bar. Both now have an explicit [hidden] override so they actually disappear when hidden instead of rendering as an empty box.

[1.12.73] — 2026-07-03

Added

Explicit "Extract Text" step for PDF import — importing a PDF now stops after loading and rasterizing its pages (fast — you can already scroll/zoom and look at it) instead of immediately and silently running text extraction. A new banner shows the page count and an "Extract Text" button; the OCR-headings checkbox now lives here since it only matters right before extraction runs. This makes the pipeline stepper's "PDF" and "Text" stops correspond to two real, distinct stages instead of one being a no-op. Reopening an already-read document from the library is unaffected — it still extracts automatically, since there's nothing to decide on a document you've already extracted before.

[1.12.72] — 2026-07-03

Added

Cross-workflow pipeline stepper — a persistent strip above Reader/Casting and Rehearser now shows the full production pipeline (PDF → Text → Cast Audiobook → Cast Characters (optional) → Script Rehearser → Generate MP3s → Audiobook) as clickable stops. Every reachable stop jumps directly to that stage without losing state — previously "Open in Rehearser" was a one-way door with no way back except hunting through the sidebar, and re-entering the casting panel could lose track of where you were.

Fixed

Casting feed silently merged pages after leaving and returning to the casting panel — page cards ("PAGE 4", "PAGE 6"...) were reconstructed on every redraw by re-guessing each segment's position via a forward-only text search against the cached source text; if a segment's text didn't exactly re-match (LLM cleanup, dehyphenation, short lines), the search stalled and every later page boundary was silently dropped, folding several pages into one card. Segments are now stamped with their real page number at cast time and the feed redraws directly from that instead of re-guessing it.

[1.12.71] — 2026-07-03

Changed

"Not synthesised" highlight no longer paints the whole book red on import — every sentence starts in the pending state, so a freshly-imported document showed wall-to-wall red before you'd asked for anything to be synthesised. The red tint (PDF overlay and text-mode word spans) now stays invisible until synthesis actually starts — clicking "Synthesise pages", pressing play, or reopening a saved document that already has some audio — at which point pending/synthesising/ready/reading colours all show normally to track real progress.

[1.12.70] — 2026-07-03

Added

Recover chapter headlines baked into a PDF as images — pdf.js's text extraction only ever sees real text glyphs, so a stylised chapter-title graphic (e.g. "1. Kapitel", "Prolog") silently vanished from the reader with no trace it was ever there. The importer now flags any page whose real text starts well below the top edge, rasterizes just that band, and OCRs it with a locally-vendored Tesseract.js worker (German + English), splicing the recognized heading back into the sentence stream so it reads aloud and highlights normally. Toggle via the new "OCR headings" checkbox above the import dropzone (on by default).

[1.12.61] — 2026-07-01

Fixed

Cascading 429s during casting/recasting — the frontend already sends attribution requests one at a time, but a client-side timeout only aborts the browser fetch; the backend's blocking call to the LLM kept running in its thread regardless, leaving a "ghost" request still occupying the LLM's processing slot. The next chunk (or a timeout's retry-in-halves) then fired into that busy slot and the LLM answered with 429, and the ghosts piled up faster than they drained. Outbound calls to the audiobook-attribution LLM are now serialized behind a backend lock so the app never has more than one real request in flight against the engine, no matter how many chunks or retries the frontend queues up.
Casting timeouts on slow/local models — the attribution request timeout (90s) was tuned for fast hosted APIs, but a local model generating at ~15 tokens/sec can take several minutes to finish a single passage (up to ~4000 output tokens), so nearly every request was aborted client-side before the model replied. Attribution, retry, recast, and warmup timeouts are all raised (90s→6min, 60s→3min, 75s→4min, 3min→4min) to match realistic local-inference generation time.

[1.12.60] — 2026-07-01

Fixed

Casting crash strands the panel and breaks the reader — an unexpected per-passage error (bad LLM response shape, mid-retry network failure) could throw uncaught out of the casting loop instead of degrading gracefully to quote-splitting for that passage. The escaped error left _audiobook.running false with the panel stuck mid-cast; clicking "Stop Casting" then navigated back to the reader, which hit an unrelated null-pointer bug while re-rendering the PDF and showed an empty import screen. Per-passage attribution is now wrapped so any unexpected error falls back to auto-detected dialogue and the cast continues or ends in the normal "stopped early" panel instead of crashing.
Character selection bar placement — reverted to sit above the casting feed (previous change had moved it below).

[1.12.59] — 2026-07-01

Added

Resume interrupted audiobook casts — a "Continue casting" button now appears after restoring an autosaved cast that was cut short (e.g. by a server crash), picking up at the passage it stopped on and keeping already-cast passages instead of requiring a full "Recast all".

Changed

Casting panel layout — the progress bar now sits at the bottom of the casting panel, just above the action buttons, with the "Live" jump-to-latest button above it instead of overlapping the top of the feed.
Casting feed reads as paginated pages — each source page in the casting feed now renders as its own card (white surface, thin border, soft shadow, margin between cards) on a neutral canvas background, instead of a plain dashed "Page N" divider inline with the text.
Casting panel element placement — the character selection bar now appears below the feed instead of above it, and the "N characters · M segments" summary now sits under the character sidebar instead of in the action-button footer.

Fixed

Stale progress bar on restored casts — reopening a finished or restored audiobook cast no longer re-shows the passage-count header and progress bar that the completed-state view had just hidden, which was also causing the "N% (Passage X of Y)" label to wrap and clip.
Interrupted casts silently reported as 100% done — manually fixing a speaker name, or stopping a "Recast unknown"/"2nd Quality Run" pass, used to overwrite the saved draft's progress with a done:-1,total:-1 sentinel that displayed as "100% complete", permanently hiding that the original cast never finished. Both now preserve the real progress instead, and a successful "Recast unknown" pass now persists its corrections (previously not saved at all).
Character selection bar showing as an empty box — .ab-char-bar set display:flex unconditionally, which beat the browser's default [hidden] rule at equal CSS specificity, so the bar rendered as an empty box even while "hidden". Added an explicit [hidden] override.
Stale static assets after edits — the app loads a prebuilt bundle (static/dist/main.min.js) in front of the individual static/js/*.js files, and the cache-busting version query string wasn't being bumped, so recent fixes weren't reaching the browser. Bundle rebuilt and version bumped to force a fresh fetch.

[1.12.58] — 2026-06-30

Fixed

Audiobook cast stalls — per-passage LLM attribution now uses bounded UI timeouts and falls back to deterministic quote detection when a passage or retry half takes too long.
LLM server responsiveness — audiobook attribution and character-sheet extraction now run blocking LLM HTTP calls in worker threads and honor a clamped timeout_seconds request value, so slow local LLM calls no longer block the whole app server event loop.

[1.12.57] — 2026-06-30

Fixed

Audiobook stop-casting flow — stopping a book-to-audiobook cast now keeps the casting panel open, aborts the active request cleanly, and preserves completed passages instead of dropping back to the empty Reader import view.
Interrupted cast drafts — partial audiobook casts now save their real completed chunk count so recovery no longer treats an interrupted cast as 100% complete.

[1.12.56] — 2026-06-30

Fixed

Engines local-card fetch race — overlapping Docker container refreshes can no longer let an older failed request overwrite a newer successful render with Could not reach server: Failed to fetch.
Engines refresh resilience — local engine cards retry once, keep the last good container list on transient network changes, and show an inline Retry button only when no cached data exists.

[1.12.55] — 2026-06-30

Added

SQLite-backed app state — server settings, TTS routes, and voice-design presets now persist through config/tts_creator.db via a shared app_state table while continuing to mirror JSON files for compatibility.
SQLite voice library index — /api/voices now reads the last indexed voice payload from SQLite and refreshes the filesystem scan in the background; first load and explicit refresh still rebuild from disk.
Voice index status endpoint — GET /api/voices/index reports index count, age, timestamp, and refresh state.

Performance

Faster voice library loads — normal voice-list requests avoid rescanning every audio/meta/reference/image file on each page load; the Refresh button uses /api/voices?refresh=1 when a full rescan is needed.
Shared voice dropdown cache — TTS backend voice options now prefer the same SQLite index before falling back to filesystem scanning.

[1.12.54] — 2026-06-30

Fixed

Engine API keys now persist — Docker/local engine card keys and cloud API cards save into server settings via engine_api_keys; Groq STT and ElevenLabs also sync to their existing first-class settings keys.
Engine settings whitelist — engine_local_urls, engine_container_names, engine_api_keys, custom_engine_cards, and fishspeech_url are now accepted by the settings API instead of being silently dropped.

Changed

Engines header cleanup — replaced the wide right-aligned header note with a compact stacked context row so Language Models, Speech Recognition, and Text to Speech headers no longer leave a large empty band.

[1.12.53] — 2026-06-30

Changed

Library frontend split — moved the Characters / Cast workspace out of static/js/library.js into static/js/library-characters.js; library.js now owns only production overview, book/play cards, and cross-links.
Removed obsolete monolith — deleted the unused tracked static/app.js; the active runtime path remains loader.js + static/js/* or the generated bundle.

Performance

Faster startup — navigation now initializes before async settings/voice refreshes, benchmark data loads only when Performance opens, and ElevenLabs browsing starts only when Get Voices is shown.
Faster voice-list rendering — batches voice-row DOM insertion with DocumentFragment and avoids rebuilding filter <select> options when the option set has not changed.
Less hidden DOM work — background voice-library refreshes update data without rendering the full voice list while the Voices section is hidden.
Faster character render wiring — replaces repeated all.find(...) lookups with an id map and batches production card insertion.

Fixed

Production bundle parity — scripts/minify.mjs now includes benchmark-voice-picker.js and library-characters.js, matching the fallback loader order.

[1.12.52] — 2026-06-30

Fixed

Uncaught TypeError in settings.js — $('voice-id-input').addEventListener crashed on load when the Clone section HTML hadn't been injected yet; guarded with ?.

[1.12.51] — 2026-06-30

Fixed

Engines not loading — loadLocalContainers() was called once at module load before the section HTML existed; now called every time the Engines section is shown and on every tab switch (all three tabs: TTS, STT, LLM)

[1.12.50] — 2026-06-30

Added

Skeleton loading for engine cards — the LOCAL section in Engines (TTS / STT / LLM tabs) now shows animated shimmer placeholder cards while querying Docker container status instead of a blank box

Performance

Parallel Docker status checks — GET /api/local-containers now queries all 25 container definitions concurrently via asyncio.gather + asyncio.to_thread instead of sequentially; reduces load time from ~25× latency to ~1× (one Docker socket call worth of time)

[1.12.49] — 2026-06-30

Added

SQLite persistence for characters and rehearsals — character library and script rehearsals are now stored in config/tts_creator.db (SQLite) instead of browser IndexedDB; data survives browser-cache clears, works across browsers/devices, and is ready for future migration to PostgreSQL/Supabase
New REST API: GET/POST/PUT/DELETE /api/characters/{id} and GET/POST/PUT/DELETE /api/rehearsals/{id} backed by core/database.py
One-time automatic migration — on first load, if server DB is empty, existing IndexedDB data is automatically exported and imported to SQLite (characters and rehearsals separately)

[1.12.48] — 2026-06-29

Added

Server-side cast persistence — after every casting chunk and after manual corrections, the full cast (segments + roster) is saved as Scripts/cast.md inside the book's server directory (config/reader_library/<id>/Scripts/); survives browser-cache clears and works across devices/browsers
Cross-device restore — audiobookOpenCastView now has a 3-tier restore: (1) in-memory, (2) localStorage, (3) server fetch; whichever fires first wins; server draft is cached into localStorage automatically
New REST endpoints: GET/PUT/DELETE /api/reader/docs/{id}/scripts/{name} and GET /api/reader/docs/{id}/scripts (list)

Fixed

Casting tab didn't restore draft on click — the "Casting" sidebar nav item called showReaderView('cast') which only shows the panel DOM; now calls audiobookOpenCastView() which runs the full restore logic

[1.12.47] — 2026-06-29

Added

Skeleton loading UI — the casting feed and "Characters Found" panel now show animated shimmer skeleton rows while waiting for results instead of a blank gray area
Version shown instantly — app version in About page is read from a <meta> tag immediately on load (no async delay); server fetch confirms it in the background

Fixed

Progress bar hidden before casting starts — the 0% bar no longer shows in the initial "Ready to cast" state; it only appears once casting begins
VERSION file updated — the server-side version was stuck at 1.12.37; now correctly reports the current version after container restart

[1.12.46] — 2026-06-29

Added

Edit pencil in casting profile — pencil icon in the top-right of the character header banner; clicking it enables inline editing of all character sheet fields (appearance, personality, history, skills, relationships) with 900ms auto-save; clicking the checkmark exits edit mode
Sources in casting profile — "Quellen im Text" section now appears at the bottom of the character profile; clicking a source page jumps to that page in the Read Aloud reader

Fixed

Progress bar hidden after casting — the yellow progress bar and passage counter disappear automatically when the casting run is complete
Profil button toggles — clicking "Profil" when the profile is already open closes it (returns to script); the button label flips between "Profil" and "← Skript"

[1.12.45] — 2026-06-29

Changed

Casting character bar — clicking a character in the casting view's character list no longer hides the feed; instead a compact bar appears above the feed showing the character's avatar, name, and dialogue-line count
All dialogue rows for the selected character are highlighted in the feed (subtle purple tint)
Prev/next navigation — up/down buttons in the bar scroll the feed to the previous or next line for that character, with a "3 / 76" position counter
Search within character lines — typing in the search box filters to matching lines and scrolls to the first hit; pressing Enter advances to the next match
Open profile button — the "Profil" button in the bar hides the feed and opens the full character sheet (voice assignment, alignment, history, etc.); the back button restores the feed and re-applies highlights
Re-clicking the same character in the list closes the bar

[1.12.44] — 2026-06-29

Added

Character detail in the casting view — the "Characters Found" list in the Read Aloud casting panel now shows colored letter-circle avatars (matching the Library view colors) instead of small pill chips; clicking any character hides the cast feed and opens their full character detail (header, voice assignment, alignment, appearance, personality, history, skills, relationships) in the feed area; a "← Zurück zum Skript" button at the top restores the feed
Voice assignment from casting panel — Auswählen, Automatisch, and Online suchen voice buttons work inline in the character detail panel; after assigning, the panel refreshes with the new voice

[1.12.43] — 2026-06-29

Fixed

Character detail page scrolls properly — .lib-char-page now has a fixed viewport height (100dvh - 148px) so the main content panel and the character sidebar each scroll independently; sidebar no longer floats outside or breaks sticky
Sidebar clearly separated — 3 px border + inset box-shadow replaces the thin 1 px line; sidebar is now 240 px wide with more padding
Source quote → reader navigation always works — clicking a source now always navigates to s-reader first; if the book is already open it scrolls to that page div (or finds the first sentence on that page via readerJumpTo); only shows a "reopen book" toast if neither source is available
Auto-assign voice respects German gender terms — gender detection now handles both English (female/male) and German (weiblich/männlich) by checking startsWith('w') as female in addition to startsWith('f'), preventing female voices from being assigned to male characters whose gender field was written in German

[1.12.42] — 2026-06-29

Changed

Character detail is now a full page, not a popup — clicking a character card opens a two-panel detail page inside the Library section; center pane shows the full character sheet, right sidebar lists all characters in the same production sorted by appearances; "← Alle Charaktere" back button returns to the card grid
All character fields are inline-editable — every text field (name, aliases, archetype, physical, backstory, relationships, etc.) is contenteditable with auto-save (900 ms debounce after each keystroke) via clPut; the moral alignment bar is now a draggable <input type="range"> slider
Source quotes in character detail are clickable — clicking a "Quellen im Text" source entry navigates to that page in Read Aloud (scrolls the reader to that page div); shows a toast if the book is not open yet

[1.12.41] — 2026-06-29

Changed

Portrait-style character cards — cards are now vertical with a colored gradient banner at the top holding the 72 px avatar; name + archetype centered below; snippet, alignment bar, and relationship dots fill the body; compact voice row with "Auswahl" / "Auto" at the bottom; grid uses minmax(200px, 1fr) so more fit per row
Voice assignment moved to top of character detail modal — the "Stimme" row is now the first thing below the header, so voice picking is always visible without scrolling
Quellen (sources) section added at bottom of detail modal — shows verbatim text quotes with page number and context label from the character sheet generation; gives evidence for each character detail
Stronger German language enforcement for character sheet generation — system prompt now starts with a bilingual ⚠️ SPRACHE / LANGUAGE block listing every field that must be in German; the user-message reminder also now explicitly says no field may be in English

Fixed

Existing character data generated in English can be refreshed by re-running "Cast Characters" from the production header — the language instruction is now strong enough that even stubborn models should comply

[1.12.40] — 2026-06-28

Fixed

Character detail modal had transparent background — var(--card) is not defined; replaced with var(--surface) and var(--panel) throughout the modal

Changed

Larger fonts and spacing in character detail modal — field values 15 px, field labels 11 px, section labels 11 px bold; alignment bar 12 px tall; avatar 90 px; alternating panel/surface backgrounds for section rows give clear visual separation
Character detail modal fully translated to German — all labels, section headings, tier names, arc descriptions, alignment descriptions, and button text are now in German (Erscheinung, Persönlichkeit, Geschichte, Fähigkeiten, Beziehungen, Konflikt & Strategie, Geheimnisse & Bogen, Moralische Gesinnung, Stimme zuweisen, etc.)

[1.12.39] — 2026-06-28

Changed

Character cards enlarged — cards are wider (320 px min), font sizes match the rest of the app (15 px name, 13 px body), avatar is 52 px, interaction dots and alignment bar slightly bigger
Click a card → full D&D/LARP character sheet modal — shows all generated fields in labelled sections: Appearance (physical + clothing), Personality (mannerisms + voice pattern), Story (backstory, motivation, fears), Skills & Abilities, Relationships (full text + interaction dots), Conflict & Strategy, Secrets & Arc; moral alignment bar is larger with score and arc label; voice assignment buttons live in the modal too; Edit and Close buttons in the header; clicking the avatar inside the modal uploads a profile picture

[1.12.38] — 2026-06-28

Fixed

Characters/Cast showed empty (only "Import" button) after character sheet generation — _charRelsHtml called .toLowerCase() on the relationships field which the LLM sometimes returns as an array instead of a string, crashing the card renderer mid-forEach. Only the toolbar bar was appended; all production groups were silently lost. Added _libStr() coercion in library.js for all rendered fields, and _clSanitize() in characters-library.js applied at both first-insert and merge time so stored data is always clean strings going forward.

[1.12.37] — 2026-06-28

Fixed

Progress dialog stuck showing "Cancel" after completion — .audiobook-overlay { display: flex } in CSS overrides the hidden attribute, so done() calling ov.hidden = true had no effect. Fixed by using ov.style.display = 'none' / 'flex' directly, same pattern as the cast panel fix.

Changed

Character sheets now navigates to Library → Characters/Cast on completion — instead of opening a read-only overlay that requires closing, finishing character sheet generation saves all sheets to the library and immediately takes you to Library → Characters / Cast where you can see the cards with alignment bars, interaction dots, and profile pictures. If results are already cached, clicking "Character sheets" again goes straight there too.

[1.12.36b] — 2026-06-28

Fixed

Character sheet descriptions generated in English for German books — the language instruction was a weak one-liner buried after a long English system prompt, so the LLM defaulted to English. Now the language rule is the very first thing in the system prompt, explicit about every descriptive field ("write all values in {language}"), and also repeated as a short reminder in the user message directly before the passage. Requires docker restart (Python change). Cache the new sheets by re-running "Character sheets" — cached results from earlier runs won't change.

[1.12.36] — 2026-06-28

Added

Profile picture on character sheets — each character card in the overlay and in Library → Characters/Cast now has an avatar area. Click it to upload any image (PNG/JPG/WebP). The image is stored as a base64 data URL in the IndexedDB character record (image field) and survives re-generation. The letter-avatar falls back when no image is uploaded. Overlay cards show an 80×80 avatar beside the name; library cards replace the coloured initial dot with the photo.

Fixed

"Passage N failed: Error" — the generic error message was caused by the JS not reading the HTTP status or response body before throwing. Now shows HTTP 502: LLM character-sheet generation failed: <reason> (or JSON parse error if the server returns non-JSON). Also logs the full error to the console for debugging.
Context window overflow on early passages — csExistingSummary was listing every missing field for all characters, which grew large quickly and could push the combined prompt over the model's context window. Trimmed to 5 key fields only (physical, backstory, motivation, voice_pattern, relationships).

[1.12.35] — 2026-06-28

Fixed

Character sheets used wrong mental model — the generation treated character discovery as its primary job, starting with an empty roster and counting "found" characters as progress. But the 45 characters are already known from the casting run. Now csForReader seeds csGenerate with _audiobook.roster (all known names from the cast) from passage 1. The LLM sees the full cast on every chunk and focuses on filling in details rather than rediscovering. Progress shows "X / 45 characters detailed" (how many have at least one filled field) instead of the misleading "1 characters found".

[1.12.34] — 2026-06-28

Added

Alignment bar redesign — replaced the text-based "◼ Evil → Good ◻" row with a proper gradient box (dark left = evil, light right = good). A white circle with a dark border marks the character's moral_alignment_score position. The arc direction arrow (↗ ↘ ↕ →) sits inside the circle and is colour-coded (green = redeeming, orange = descending, purple = complex). Arc note text appears below.
Character sheet progress: character counter — the progress overlay now shows a live "X characters found · Y complete" line below the passage progress bar, updating on every passage.
Image prompt button on each character card — copies a Stable Diffusion / ComfyUI portrait prompt built from physical description, clothing, archetype, gender, and moral alignment to the clipboard.
Voice prompt button on each character card — copies a voice design instruction built from voice_pattern, mannerisms, archetype, gender, and moral tone to the clipboard; ready to paste into Design a Voice.

Fixed

[object Object] in Physical / Relationships fields — when the LLM returned an array or nested object for a scalar field the value was stored as-is and rendered via String() as [object Object]. Added _csStr() sanitiser that joins arrays with ", " and falls back to JSON.stringify for any other non-string value; applied at both initial insert and merge in csMerge.

[1.12.33] — 2026-06-28

Fixed

Blue box after "Recast Unknown → no unknown found" — audiobookCastView() set panel.style.display = 'flex' as an inline style. When showReaderView('main') later set cast.hidden = true, the inline style won the specificity battle and the panel remained visible as a large empty box. Fix: clear the inline display style on hide, and stop setting redundant inline flex styles (the .ab-castpanel-inline CSS class already defines display:flex; flex-direction:column).

[1.12.32] — 2026-06-28

Added

Alignment bar on character cards — each character card in Library → Characters / Cast now shows a compact good↔evil gradient bar with a white dot positioned at the character's moral_alignment_score (0 = evil / black end, 100 = good / light end). An arc arrow beside it shows the character's trajectory: ↗ (redeems), ↘ (descends toward evil), ↕ (complex arc), → (stable).
Most-interacted characters — below the alignment bar, up to 5 small coloured avatar dots show which other characters in the same production are most-mentioned in this character's relationships field. Each dot's colour matches that character's avatar and shows name + mention count on hover.

[1.12.31] — 2026-06-28

Added

Read Aloud submenu — "Read Aloud" in the sidebar is now an expandable tree with two sub-items: Reader (PDF view) and Casting (jumps directly to the casting panel for the open book).

Fixed

Character sheets "passage 1/1" / No characters found — generation.js (which defines splitTextIntoChunks) was missing from the production bundle. When the bundle was active, character sheets always fell back to sending the entire book as a single LLM call, which almost always returned nothing for large texts. generation.js is now included in the bundle (21 modules, 701 KB).
Copy active → Copy selected — the "Copy active" button on the voice library toolbar now copies the checked/selected voices when any rows are checked, and falls back to all active voices only when nothing is selected. Label and toast reflect which mode was used.

[1.12.30] — 2026-06-28

Fixed

Audiobook casting lost when reopening a book — the cast autosave was stored under one global key and validated only by a fingerprint of the extracted text. Reopening a large PDF re-extracted text that drifted slightly, the fingerprint mismatched, and the whole cast was discarded as a "different document". Drafts are now keyed by the book id, so reopening the same book always restores its cast regardless of text drift (the text fingerprint remains a fallback for ad-hoc documents).
Opening a book dropped into an empty casting panel — a leftover cast panel from a previous session hijacked the reader via the nav restore logic. Opening a book now reliably lands on the PDF (main) view; the stale-cast restore is suppressed for a fresh open. Click "Cast as Audiobook" to restore that book's saved cast.

Added

Voice matching from the cast cards — each character in Library → Characters / Cast now has, beside Pick/Auto, an Online button (opens Get a Voice Online on the Fish.audio tab, pre-filled with the character name + detected language) and a Generate button (opens Design a Voice pre-filled with the character's gender, language, name, and a voice description built from the sheet).
Automatic language detection — a dependency-free detectLang() (script ranges + stop-word frequency for de/en/fr/es/it/pt/nl) auto-fills the document language during character extraction when left on Auto, and drives the language pre-fill for online search / voice design.

[1.12.28] — 2026-06-28

Added

SillyTavern character-card compatibility — import and export characters in the SillyTavern / TavernAI "Character Card" format.
- Import accepts V1 (flat JSON), V2 (chara_card_v2), and V3 (chara_card_v3) cards as .json, plus .png cards with the JSON embedded in a PNG tEXt chunk (chara/ccv3). A gender heuristic fills the field when the card omits it. Available globally and per-production in Library → Characters / Cast.
- Export writes a V2 JSON card per character (universally accepted by SillyTavern, Chub, AI Character Editor, …). The assigned TTS voice is stored under data.extensions.tts_voice so a round-trip preserves the casting.

Fixed

Huge empty box / content pushed to the middle — when the voice API was slow and the 8-second loader fallback fired, it hid the loading skeleton with opacity:0 but left the element in the DOM (still occupying ~700px) and caused later cleanup to skip removal. The skeleton is now fully removed from the DOM in every path, and .sk-hidden also sets display:none.

[1.12.26] — 2026-06-28

Fixed

Sidebar blue highlights on wrong items — "Language Models", "Books", "Stage" were hardcoded is-active in HTML and stayed blue even when on a different section. Added CSS rule [data-nav-section]:not(.active) + .nav-tree .nav-tree-item.is-active to suppress sub-item highlight whenever the parent section-head is not current.

Added

Characters / Cast page — Library → Characters / Cast is now a dedicated production-grouped view instead of redirecting to the generic Characters section. Shows all books/scripts that have characters, with each character displayed as a card containing their character sheet info (archetype, personality snippet), tier badge (Main/Supporting), gender icon, and a voice assignment row with Pick and Auto buttons.
Voice picker in character cards — "Pick" opens a compact inline popup with searchable voice list filtered by character gender. "Auto" assigns the highest-rated unassigned matching-gender voice automatically.

[1.12.25] — 2026-06-28

Added

Library skeleton loading — Books and Theater Plays tabs now show animated placeholder cards while data loads instead of a blank panel.
Cast Characters button in audiobook completion footer — triggers character sheet generation from the casting panel.
Characters/Cast nav in Library now navigates directly to the Characters section.
Return to cast audiobook — navigating back to Read Aloud via the sidebar now restores the active casting panel if a cast session was in progress.

[1.12.24] — 2026-06-28

Fixed

Infinite skeleton hang — if any script failed to load (ERR_NETWORK_CHANGED, DNS failure, etc.) the async loader threw, skeleton-removal code never ran, and the UI was stuck for the entire browser session. init.js and nav.js are now wrapped in try-catch; _revealApp() always runs. Added an 8-second hard timeout as an absolute fallback.

Performance

Bundle enabled by default — loader now always tries main.min.js first (one request instead of 21 individual files). Falls back to per-file loading only if the bundle is missing.
Eliminated /api/version blocking round trip — version string is read from the already-loaded style.css link tag (synchronous, zero latency). Fetching /api/version was the first awaited call and blocked the entire load sequence.
JS cache restored — JS files now use only the version string for cache-busting (not version-timestamp). The session timestamp defeated the service worker cache on every reload; now the SW serves JS from cache on subsequent visits.

[1.12.23] — 2026-06-28

Fixed

Reader-main-view bleeds through casting panel — #s-reader #reader-main-view { display: flex } overrode the UA [hidden]→display:none rule. When the audiobook cast panel is shown and JS sets reader-main-view.hidden, the element stayed rendered (as a 34px tall flex strip) and bled into the cast view. Added [hidden] { display: none } specificity override.
Card collapse chevron invisible — .card-chev::before { content: '▾' } didn't render in all browsers. Switched to mdi mdi-chevron-down MDI icon class, consistent with the rest of the UI.
Sidebar sub-item highlights showing for non-current sections — added CSS sibling rule so is-active sub-items (Stage, Books, Language Models) only show accent colour when their parent section IS the current page.
Background process indicator — window.setNavBusy(sectionId, true|false) now shows an animated dot on the nav item when Read Aloud is playing.

[1.12.22] — 2026-06-28

Fixed

toggleNavTree is not defined — sidebar tree toggles can fire before nav.js executes on slow/interrupted loads. An inline stub now handles the click immediately (reads/writes ttsvc_trees in localStorage, toggles CSS classes directly); nav.js overwrites it with the full implementation once loaded.
"Saved PDF data missing" dead end — when a book's source PDF failed to upload at save time (e.g. network interruption), clicking the library card now opens a file picker so the user can re-select the original file. The PDF is re-uploaded to the existing book slot and the book opens immediately.

[1.12.21] — 2026-06-28

Changed

Casting feed — progressive expand — clicking a "N lines hidden" divider now reveals only 20 lines at a time and leaves a new divider for the remainder, so the view stays anchored and the user doesn't lose their place.

[1.12.20] — 2026-06-28

Performance

Voice list sessionStorage cache — voices are written to sessionStorage after every successful fetch (ttsvc_vc). On the next page load the list renders instantly from cache while the fresh fetch runs silently in the background. The Refresh button clears the cache first to guarantee a clean reload.

[1.12.19] — 2026-06-28

Fixed

Voice list flicker on load — engines.js (batch E) calls loadVoiceLibrary() after nav.js already rendered voices, causing the list to blank out and reload. Second call now runs silently (no skeleton, no status reset) when voices are already present.

[1.12.18] — 2026-06-28

Fixed

Diagnostic code removed — temporary debug IIFE and renderVoiceList try-catch scaffolding cleaned out of voice-library.js; My Voices loads correctly.
Settings load crash: renderSettingsAbout is not defined — loadSettings() called renderSettingsAbout() unconditionally but that function lives in conversation.js (batch E, loaded after init). Guard added with typeof check; the About section still renders when opened (nav.js already guards the same call).
Duplicate element IDs — s-library.html Characters panel duplicated cl-book-filter, cl-search, cl-grid from s-characters.html, causing getElementById to return the wrong element. Characters tab in Library now shows a redirect placeholder instead.
Infinite recursion in loadVoiceLibrary — window.loadVoiceLibrary = () => loadVoiceLibrary() overwrites the global binding that the arrow function references, causing immediate stack overflow. Changed to direct assignment window.loadVoiceLibrary = loadVoiceLibrary.

[1.12.17] — 2026-06-28

Fixed

Settings load crash — loadSettings() used direct .value assignments on elements that no longer exist after the Library restructure; all now use null-safe sv() helper so a missing element is silently skipped instead of throwing. This was also preventing My Voices from loading on page start.

[1.12.16] — 2026-06-28

Added

Batch benchmark → My Voices sync — after a batch benchmark run completes, results are automatically saved to each voice's meta.json via POST /api/voice/meta, and My Voices Factor + WPM columns update immediately without a manual page refresh.

[1.12.15] — 2026-06-28

Added

Lang + Gender in Benchmark batch results — two new sortable columns after Voice.
Lang + Gender in voice selection list — flag emoji and gender symbol shown on each voice row.
Sortable batch results table — click any column header to sort; arrow indicator shows active sort direction. Defaults to Factor descending (fastest first).

[1.12.14] — 2026-06-27

Changed

Voices table: simplified to only Factor + WPM from benchmark data (Length, Duration, Time removed — detail lives in Setup → Benchmark).
Setup → Benchmark batch results: now shows Duration, Factor (sorted descending, green ≥ 1.0×), Time, and WPM alongside existing Latency/Best columns. Factor replaces Avg RTF (same data, more intuitive direction).

[1.12.13] — 2026-06-27

Changed

Speed column split into Factor + Time: the old 21.8s · 1.30x cell is now two separate sortable columns — Factor (1.30x, audio÷render, colour-coded green/amber/red) and Time (21.8s, total render time). Column order: Length · Duration · Factor · Time · WPM · Seed · dBFS · Type · Source · Rating · Tags · Note · Active.

[1.12.12] — 2026-06-27

Added

Duration column in the voice table — shows the length of the synthesised benchmark audio (e.g. 11.4s), sortable. Distinct from Length (original clip) and WPM (speaking rate).
Benchmark sentence presets dropdown — four ready-made sentences (DE narrative, EN narrative, DE pangram, EN tongue-twister) plus a Reset option. Selecting a preset loads it instantly without overwriting anything else.

Changed

Column order rearranged to: Img · Play · Name · Lang · Gender · Length · Duration · WPM · Speed · Seed · dBFS · Type · Source · Rating · Tags · Note · Active.

[1.12.11] — 2026-06-27

Fixed

Speed and WPM cells now update live during a benchmark run — each row's cells are patched in-place immediately after its voice finishes, without waiting for the full batch to complete and the list to re-render. Same fix applied to the single-voice "Benchmark this voice" button.

[1.12.10] — 2026-06-27

Added

WPM column in the voice table — shows how fast a voice speaks in words per minute, calculated from the benchmark audio duration and sentence word count. Sortable. Hover for a tooltip explaining the range (130–180 wpm is natural for audiobooks).
Info (ⓘ) icons on the Speed and WPM column headers with tooltips explaining what each metric measures.

[1.12.9] — 2026-06-27

Changed

Benchmark speed factor shows 2 decimal places (1.32× instead of 1.3×) in the SPEED column and live status line — more precise RTF comparison across voices.
Sorting by Speed now sorts by the RTF factor (faster voices first) instead of by raw synthesis time — voices with a higher × multiplier rank higher regardless of how long the benchmark sentence was.

[1.12.8] — 2026-06-27

Changed

SOURCE column auto-derives script name for Rehearser clones: voices cloned from a Script Rehearsal now automatically display the script title (e.g. Script, her) in the SOURCE column, extracted from the note field (Rehearser · <title> · <character> — …). No manual entry needed; setting an explicit origin still takes priority.

[1.12.7] — 2026-06-27

Added

Editable Source field in the voice inspector panel (below Note) — type a source label (e.g. fish-audio, cloned) and it saves immediately to the voice's meta.json. Changes now persist across refreshes.
Bulk "Set source" button in the multi-select toolbar — select any number of voices and apply a source label to all at once.
Fish-audio tag fallback in the SOURCE column: voices tagged fish-audio automatically show fish-audio as their source even without an explicit origin field, so the column is populated correctly without having to edit every voice.

[1.12.6] — 2026-06-27

Added

Audiobook auto-saves to Script Rehearser: when casting completes, the result is automatically written to the Script Rehearser IndexedDB (same format, same library). The record is updated — not duplicated — whenever speaker corrections are made in the cast view. The record appears immediately in Script Rehearser → Library.
"Edit in Rehearser" button: replaces "Review & cast" in the completed cast panel. Opens the saved record directly in Script Rehearser with all speakers, voices, and page markers intact, ready to assign voices and synthesise.
Voice assignments made in Script Rehearser are preserved when the audiobook auto-saves again (only the script text and emotions are overwritten; voice/instruct/soul fields survive the update).

[1.12.5] — 2026-06-27

Added

Autosave for audiobook casting: progress is saved to localStorage after every passage. A page refresh, browser crash, or accidental close no longer loses hours of casting work — reopening "Cast as audiobook" for the same document restores the session automatically with a banner showing how far it was completed and when it was last saved. Manual speaker corrections made in the cast view are also autosaved immediately. The draft is cleared when the script is explicitly saved to Script Rehearsals.

[1.12.4] — 2026-06-27

Added

Expandable context dividers in Recast Unknown: the ⋯ gaps between scattered Unknown segments now show a count ("42 lines hidden — click to expand") and expand inline on click, revealing all segments between two Unknown passages so the user can see who is speaking before and after to make a better assignment.

[1.12.3] — 2026-06-27

Added

Casting activity indicator: pulsing blue dot on the Read Aloud nav item while audiobook casting is in progress, so users can see it's working from any section.
Restore cast view on return: navigating away during casting and then back to Read Aloud automatically restores the casting panel instead of showing the blank PDF view.

Fixed

Character count out of sync on reassignment: reassigning a segment's speaker now decrements the old speaker's count in the Characters Found panel, so totals stay accurate when corrections are made. Speakers that drop to 0 lines are removed from the panel automatically.

[1.12.2] — 2026-06-27

Added

PDF Search: search input in the Read Aloud toolbar — press Enter to jump to the first page containing the term, Shift+Enter to go back.
Noise gate slider: adjustable minimum-amplitude threshold in the Conversation input bar (the blue marker on the level meter shows the current gate). Short noise spikes below the gate or bursts shorter than 300 ms are silenced before STT. Persists across sessions.
Conversation stats panel now has a collapse button (→) to hide the latency sidebar and give more chat space; a floating icon button restores it.

Changed

Sidebar tooltip now extracts text correctly for all item types (sub-items that had no .nav-label span showed nothing before).
Active section in the sidebar now gets a blue background highlight + right-border accent (.nav-tree-item.active was previously unstyled, making it impossible to tell which section you were in).
Casting audiobook: LLM prompt now explicitly handles ?« and !« as valid German quote endings, and instructs the model to treat an unclosed » at end-of-passage as dialogue. Deterministic fallback also handles the unclosed-quote edge case.

[1.12.1] — 2026-06-27

Changed

Sidebar icon-rail: hover no longer flies out the whole sidebar (which caused the main content to jump left/right). Individual item labels now appear as a small floating tooltip next to the hovered icon, keeping the rail at a fixed 56 px and the layout completely stable.

[1.12.0] — 2026-06-27

Added

Slim icon-rail sidebar: the button where the flag used to be collapses the sidebar to a narrow icon rail (desktop); hovering the rail flies the full menu out as an overlay (titles + nested items). State persists.
Language picker moved to Settings → General (was the sidebar flag). English / Deutsch.
Collapsible settings panels (using the app's standard card collapse style) to free vertical space: Conversation engine/prompt config, Read Aloud voice & synthesis settings (with the drag-&-drop inside), the Try It Out voice/playback box, and the Casting-audiobook LLM/prompt panel (prompt collapsed by default).

Changed

Read Aloud layout reorganised: collapsible settings + drag-&-drop on top, zoom toolbar above the document, the document as the central area that fits the viewport height, transport + synthesis controls below it (always visible — only the document scrolls).
Read Aloud "My Books" card removed — saved books now live in the combined Library → Books.
Conversation Playground fills the viewport height (only the chat scrolls), and the config stacks full-width.
Collapsible-card initialisation now also runs when a section opens, so lazily-loaded sections get consistent collapse chevrons.

Fixed

Conversation microphone failed intermittently ("EBML header parsing failed") in hands-free/live mode: a silence reset cleared the recording buffer in place, dropping the webm header so later utterances were undecodable. The recorder now restarts cleanly, keeping every utterance valid. (Recordings are also decoded in-browser to 16 kHz WAV, bypassing server ffmpeg.) Barge-in (interrupt the agent while it speaks) works via the Live agent toggle.
Casting-audiobook overflow: a long unbroken passage string widened the layout and pushed the sidebar off-screen; the feed now wraps and is width-constrained.

[1.10.1] — 2026-06-27

Added

Collapsible nested sidebar: group headers Voice Actions, Speak and Setup are now expandable parent menus; Tags nests under Library, and Integrations (App Routing · Connect Apps) and Settings nest under Setup. Opening a section auto-expands its whole ancestor chain.

Changed

Conversation Playground config stacks full-width — Speech to Text, Language Model, Text to Speech and System Prompt each on their own row for clarity.

Fixed

Conversation microphone failed with "Audio upload failed: Decoding failed / EBML header parsing failed" on ARM64: recorded audio is now decoded in the browser and uploaded as 16 kHz mono WAV, bypassing the server-side ffmpeg webm parser entirely (falls back to the raw blob if browser decoding is unavailable).

[1.10.0] — 2026-06-27

Added

Combined Library (new Library section under Speak) with three tabs — Books, Theater Plays, Characters / Cast — bringing audiobooks, rehearsals and the character roster into one place. Book and play cards cross-link: Rehearse a book, Read Aloud a play.
Character tags (like voice tags): each character carries a comma-separated list of productions, seeded with its origin book and editable in the character editor. A character can now be reused across several books/scripts — one record, many tags.
Shared cast resolution: opening a production in the Rehearser (and audiobook casting, which routes through it) auto-fills empty cast slots from the shared character roster, matched by book or tag. Cast voice choices are written back to existing characters on save, keeping the roster in sync. Productions are joined by normalized title (prodKey).
Tags navigation group under Voices: distinct voice tags with live counts, plus the Cloned / Designed / Favourites predicates, each filtering the voice list.

Changed

Sidebar restructured into clearer groups: Voices (Library · Tags · Voice Actions), Speak (Quick Play · Conversation · Read Aloud · Script Rehearsal · Library), Setup (Benchmark · Engines · Integrations · Settings). "Try It Out" is now Quick Play; "My Voices" is now Library.
The standalone Characters section was folded into the combined Library; Read Aloud is now a single entry (its library lives in the combined Library); the Rehearser's Library/Cast steps moved into the combined Library, leaving Stage · Summary · Import/Export in the sidebar.

[1.9.8] — 2026-06-27

Changed

Seed Finder default sentence: updated to a longer mixed DE/EN test phrase covering numbers with dots (3.567), compound nouns, umlauts, special characters, English technical vocabulary, time formats, and motivational prose — gives a more complete picture of a voice's character per seed.

[1.9.7] — 2026-06-27

Fixed

Voice inspector broken: curGender was referenced before its const declaration inside selectVoice(), causing a temporal dead zone ReferenceError that silently prevented the inspector from opening. Clicking a voice now correctly opens the detail panel again.
Batch operations ignore selection: Calc dB, Precompute, and Batch Seeds now operate only on the checked (selected) voices when a selection is active, matching the existing behaviour of Benchmark. Previously all three always ran on all active / visible voices regardless of selection.

[1.9.6] — 2026-06-26

Fixed

Casting feed — scroll hijacking: the feed no longer forces the view to the bottom while you are scrolled up reviewing or editing earlier lines. Auto-scroll only fires when you are already within 80px of the bottom.
Casting feed — vanishing text: the trimming limit was raised from 80 to 600 rows, and trimming is now suppressed while you're scrolled up, so older lines stay visible as long as you're looking at them.

Added

Casting feed — "↓ Live" jump button: a floating pill button appears at the bottom of the feed whenever you've scrolled up. Click it to immediately return to the live bottom of the feed and re-enable auto-scroll.

[1.9.5] — 2026-06-26

Added

Casting view — page-break lines: as the LLM processes a PDF audiobook, a "Page N" divider row now appears in the casting feed whenever the source PDF page changes. This gives a live view of where each page boundary falls within the script.
Casting view — expandable LLM passage panel: the "LLM Reading…" indicator now shows a preview of the passage being processed. A chevron button (▾/▴) expands it into a full scrollable view of the passage text so you can follow exactly what the LLM is reading and thinking about.

Fixed

Page numbers were off by one: page-break markers emitted into the Rehearser script now use the correct 1-indexed PDF page number (was storing 0-indexed, so "Page 1" showed for what was actually the second PDF page).

[1.9.4] — 2026-06-26

Changed

Audiobook casting — page numbers in Rehearser: page-break markers now carry the source PDF page number. In the Script Rehearser Stage, each page divider shows "— Page N —" instead of the generic "— Page break —", making it easy to cross-reference the audiobook script against the book. Applies both to audiobooks cast from Read Aloud PDFs and to screenplay PDFs imported directly into the Rehearser.

[1.9.3] — 2026-06-26

Added

Native Speed for Try it out & Read aloud: a Native Speed control (range 0.5×–2.0×, default 1.0) is now available in both the Try it out and Read aloud sections. It passes the speed parameter directly to the TTS generation request (natively via the faster-qwen3-tts backend), producing audio at the target tempo from the model rather than using post-processing pitch/time-shift. Try it out persists the chosen speed in localStorage (per browser); Read aloud saves it with the document in the library (each book remembers its own speed).

[1.9.2] — 2026-06-26

Fixed

Audiobook casting — pagination preserved on save: saving (or opening) a cast audiobook as a Script Rehearsal now keeps the book's page breaks. Read-aloud page boundaries are tracked through casting and re-emitted as \f markers at the nearest segment boundary, so the Rehearser paginates the saved script to match the source PDF instead of producing one continuous flow.

[1.9.1] — 2026-06-26

Fixed

Character sheets — "Connection refused" failures: the analysis could send a dead localhost:11434 LLM URL to the server (when app settings hadn't loaded yet), causing every passage to fail. It now never falls back to that hard-coded default — when no endpoint is explicitly chosen it lets the server use its own configured llm_url, so character-sheet extraction uses the same working LLM as the rest of the app.
Audiobook casting — empty "Review & cast" preview: opening the manual-correction preview after a cast rendered no lines because the name-highlighter (highlightText) was scoped to the live cast view only. It is now shared, so you can review, fix speakers/emotions, and open in the Rehearser again.

Changed

Script Rehearser / Stage — one text size: narrator (action) text and spoken dialogue now use the same font size instead of mismatched 15px/16px, so the play reads evenly.
Script Rehearser / Stage — text-size control: a new A− / A+ control in the Stage toolbar shrinks or enlarges the whole play (persists per browser), in both A4 and paginated/scroll views.
Script Rehearser / Stage — collapsible character list: the row of cast chips can now be collapsed or expanded via a "Characters (N)" toggle to free up vertical space.

[1.9.0] — 2026-06-26

Added

Character Library: a new Characters section in the sidebar collects every character the LLM extracts into a persistent, browsable library (IndexedDB), grouped by the book or script they came from. Running Character sheets from Read Aloud or the Script Rehearser now auto-saves each character (keyed by book + name), merging in new detail on re-runs. Each card can be edited inline or deleted, and keeps its greyscale Good↔Evil alignment bar, arc arrow, page/line sources, and the 5-area psychological Deep Analysis. New module static/js/characters-library.js.
Richer character sheets: extraction now gathers six more book-derived fields per character — Backstory & Origin, Relationships, Motivation, Fears, Mannerisms & Habits, and a casting-focused Voice & Speech pattern (accent, pacing, register, verbal tics).
Character sheets — morality at a glance: each sheet now shows a greyscale Good↔Evil alignment bar (white = good, black = evil) with a 0–100 score, plus an arc arrow indicating whether the character stays put, descends (↘ good→bad), redeems (↗ bad→good), or follows a complex (↕) path. Also added Clothing & Appearance and Capabilities fields and richer physical detail (height, hair, eyes, skin, gait), with sources now carrying a short category line hint.
Character sheets — Deep Analysis: a per-character button runs a 5-area psychological & narrative study (Core Flaw & Desire · Agency & Passivity · Dialogue & Voice · Narrative Arc · Paradox & Depth) in a modal. New endpoint POST /api/character-deep-analysis.
Audiobook casting — Recast & rescue tools: after a cast run you can now Recast all (re-run the whole document with tweaked settings/prompt), Recast unknown (re-attribute only the leftover Unknown lines using surrounding context), run a 2nd Quality Run — Verify pass that re-checks every speaker assignment and resolves Unknowns, and Save script straight to Script Rehearsals without leaving the page.

Changed

Recast unknown — passage separators: re-analysing only the Unknown speakers now shows a ⋯ divider between non-adjacent passages, so it's clear where one excerpt ends and another begins.
Dialogue attribution — fidelity & language: the attribution prompt now forbids hallucinating/summarising (segments must reconstruct the passage word-for-word), emits emotion tags in the same language as the text (e.g. German wütend/flüsternd), and demands strict JSON. Removed the brittle text-script fallback parser that could mis-split prompt echoes into fake speakers.

1.8.1 — 2026-06-25

Added

Audiobook casting — Warmup request: Added an invisible "Wake up" request before starting the attribution loop, showing a clear "Waking up LLM model..." status. This absorbs the 3–4 minute cold-boot time of massive models (like 120B/30B via llama-swap) without freezing the UI or timing out the first real book chunk.
Audiobook casting — Quick-cancel: The character assignment popup now has a close button and responds to the Escape key, so you can easily dismiss it if you click "Assign" by accident.

Changed

Audiobook casting — Narrator quick-pick: The 📖 Narrator role is now always pinned to the top of the manual assignment dropdown list, so you don't have to scroll or type to revert a mis-cast line to narration.
LLM timeout increased: The hardcoded API timeout in routes/conversation.py for all LLM calls has been increased from 3 minutes to 10 minutes (timeout=600), providing plenty of headroom for dynamic model proxies to download and load models into VRAM on demand.

Fixed

Read Aloud — "Fit width" scaling bug: Clicking "Fit width" on PDFs with a small cover page (e.g. A5) but larger subsequent pages previously zoomed the cover perfectly but blew the text pages up massively (e.g. 241%), forcing horizontal scrolling. The scale is now computed against the maximum width of all pages, guaranteeing the entire book fits.
Read Aloud — Left-side text cut-off (CSS bug): Fixed a flexbox centering issue on the document container where a zoomed PDF page that was wider than the screen would overflow equally on both sides. Because browsers only scroll to the right, the left edge of the page was permanently inaccessible. Fixed by replacing align-items: center with margin: 0 auto.
Audiobook casting — Minified bundle caching: Features added directly to JS files weren't appearing because the app was serving an older, cached minified bundle. The bundle has been rebuilt and version cache-busting ensures the new UI shows up immediately.

1.8.0 — 2026-06-22

Added

Seed Finder — pin a specific seed: a direct “fix this voice to a specific seed” control (type a seed → Pin, or Unpin to go back to random) that saves straight to the TTS server without generating anything — handy when you already know the seed you want.
Seed Finder — persistent pinned seed indicator: the pinned seed is now saved locally in the voice's metadata and displayed prominently in the voice inspector header. It automatically restores the "Pin seed" input when reopening the voice.
Seed Finder — batch all voices: a Batch seeds button in the voice toolbar pre-generates and caches Seed Finder samples for every active voice. An in-app dialog (no browser pop-ups) lets you set the seed range with a live sample-count estimate, then shows live progress (current voice/seed) with cancel. Runs sequentially, skips already-cached seeds (resumable), and feeds the same cache the per-voice Seed Finder reads.

Changed

Seed Finder — samples are cached: generated seed WAVs are saved in the browser (IndexedDB) keyed by voice + test sentence + backend, so reopening a voice shows previous results instantly and re-running only generates the missing/failed seeds instead of all of them. Added a Clear saved button to drop a voice's cache.
Seed Finder — better test sentence: a shorter default sentence that exercises all German umlauts (ä ö ü ß), numbers, and a few English words — quicker to generate and more revealing of a voice's character.

Fixed

Couldn't change a voice's displayed name: the big name in the voice inspector was just the last segment of the voice ID (so DE_F_Privat_Laura_01 showed as 01), and double-clicking it renamed the ID, not the shown name. Double-clicking the header now edits a real display name (saved to the voice's metadata via /api/voice/meta, persists across reloads) and pre-fills with the current name; the separate edit ID button still renames the underlying voice ID. (Designed voices without a reference file don't support a stored display name yet.)
About page showed v0.0.0 and a stale changelog: the deployment stack wasn't mounting VERSION/CHANGELOG.md, so the container had no live version file (fell back to 0.0.0) and served the image's baked changelog. Both files are now bind-mounted in docker-compose.yml and portainer-stack.yml, so the About page reflects the running version and changelog.
Seed Finder — “Failed to fetch” seeds: long per-seed generations that intermittently dropped now auto-retry (2 attempts), each failed seed gets its own Retry button, and because successful seeds are cached, a second Run fills only the gaps rather than redoing everything.

[1.7.0] — 2026-06-21

Added

Seed Finder — in My Voices, each voice's inspector has a 🎲 Seed Finder panel: generate a sample for a range of seeds (the TTS engine produces a slightly different take per seed), play each result, and click ★ Use seed N to pin your favourite — saved immediately to the TTS server's voices.json. New /api/tts-voice-seed proxy, module static/js/seed-finder.js.
Voice library — Precompute embeddings: a Precompute button warms all active voices so the TTS engine builds and caches each voice's speaker embedding (.pt) ahead of time, making the first playback of a voice instant (better Time-To-First-Audio) instead of paying the one-time analysis cost on first use. Runs with bounded concurrency, progress, and cancel. (The faster-qwen3-tts engine already prefers a cached .pt and auto-creates it from the reference wav when missing — the wav stays the source of truth; this just pre-warms the cache.)
Character sheets — a Character sheets button in both Read Aloud and the Script Rehearser uses your configured LLM to extract actor-facing, RPG-style profiles for every character: Archetype, Physical Stats (metric-only), Alignment & Ethos, Core Attributes (highest/lowest), Trained Skills, Signature Inventory, Dark Secret / Fatal Flaw, Conflict Style, and Win Condition. Deduced details are marked with *, characters are grouped main vs supporting, and each sheet cites its sources (page number from the PDF + a short verbatim quote). Long texts are processed in chunks and merged per character (fields filled in, inventory/sources de-duplicated). Results render as scannable cards in an overlay with Copy as Markdown, and are cached so re-opening is instant. New endpoint POST /api/character-sheets, module static/js/character-sheets.js.
Book → multi-speaker audiobook — a Cast as audiobook button in Read Aloud turns a novel into a cast-able script. An LLM scans the current scope (selection / page range / whole book, chunked with a running character roster so the same speaker keeps one name throughout) and attributes every segment to a Narrator or a character, with a per-line emotion. New endpoint POST /api/attribute-dialogue and module static/js/audiobook.js; reuses the rehearser's casting, per-line tone, and synthesis. Failed chunks fall back to narration so a book always casts; progress is shown and cancellable.
- Live casting view: while attributing, a wide, non-blocking, minimisable panel shows a scrolling feed of each line with its assigned speaker (and emotion) plus a character roster that fills up with per-character line counts — instead of a bare modal progress bar. You can minimise it and keep using the app (any tab), then re-open to watch progress; when it finishes it parks as a "✓ Review & cast" panel rather than auto-popping, so it waits for you if you wandered off.
- Calmer messaging: a passage the LLM can't attribute is no longer shown as a red "attribution failed: Error" toast — it's a quiet "read by the narrator" note in the feed, with a single neutral summary ("N passages had no detected dialogue") in the review step.
- Editable preview: before handing off, a review overlay lists every segment with an editable speaker (autocompletes from detected characters) and emotion so mis-attributions are fixed in seconds; "Open in Rehearser" applies the edits and lands you at the Cast phase.
- Audiobook export (rehearser): an Audiobook button synthesises every cast line as MP3 (bounded concurrency, progress, cancel) and downloads one MP3 per chapter (split on Chapter/Kapitel/Part/Prologue… headings or act/scene markers), or a single file when no chapters are detected.
- Saved as a reopenable rehearsal: handing the cast off to the Rehearser now also saves it to the Script Rehearser library (Bibliothek) automatically, so the attributed script + cast + per-line emotions persist — reopen it anytime to change speakers/voices/lines and synthesise or export the audiobook.
Read Aloud — a new sidebar tab that turns the app into a text-to-speech document reader. Import a PDF (rendered to its real page layout via pdf.js) or a .txt / .md file, pick any voice + backend and a reading speed (0.5×–2×), then press play: the document is read sentence-by-sentence while the word being spoken is highlighted in place (overlay box on the PDF page, inline highlight in text mode), with the view auto-scrolling to follow. Click any word to jump there. Reuses the rehearser's word-timing + pdf.js loader and the existing /api/tts-preview pipeline — no backend changes. New files static/sections/s-reader.html and static/js/reader.js.
Read Aloud — synthesis-state overlay: every sentence is colour-coded by state — red (not synthesised), yellow (synthesising), green (ready/cached), blue (currently reading) — shown as a translucent overlay on the PDF page and as a tint in text mode, with a legend.
Read Aloud — PDF zoom controls: Fit width, Fit height, Two-page spread, and zoom in/out with a live percentage. Word geometry is stored scale-independently so zoom re-renders instantly and highlights stay aligned; fit modes track window resizes.
Read Aloud — resume: the last reading position is remembered per document, so re-opening the same file resumes where you left off.
Read Aloud — book library: Save to library stores the original PDF/text together with its synthesised audio and reading position in the browser (IndexedDB). A "My books" shelf lists saved documents with audio- and read-progress bars; reopen one to continue right where you left off with the already-synthesised pages intact — handy for working through long books. Reading position auto-saves on pause / stop / leaving the tab.
Read Aloud — MP3 storage & export: audio is now synthesised and stored as MP3 (far smaller than WAV, so books fit comfortably in the browser library). An Export MP3 control downloads the synthesised audio as one file per page (sections combined) or one file per sentence, with meaningful filenames like Title - p01 - 03.mp3 / Title - p01.mp3. Any not-yet-synthesised sentences in scope are rendered first.
Read Aloud — voice consistency: addresses the slight timbre/prosody drift you hear when each sentence is generated separately. A "Voice consistency" selector synthesises in larger continuous chunks — per sentence (responsive), per paragraph (steadier), or per page (steadiest) — so a whole passage is one generation. Optional Seed and Temperature inputs pin the generation (forwarded to backends that support them, with graceful fallback), Normalise loudness evens out volume between chunks on playback, and a backend hint flags cloned/zero-shot engines that re-sample per request and suggests remedies. Chunk mode + seed/temperature/normalise are saved with library books.
Read Aloud — synthesise ahead: a Synthesise button pre-renders audio for gap-free reading, scoped to all, a page range (PDF), or a click-selected sentence range. Select mode is a guided, persistent step flow — click a start sentence (it pulses as the anchor), then the end; the mode stays active with step hints so you can keep refining, and you leave it with the Done button or Esc. Synthesis runs with bounded concurrency, shows progress, and can be cancelled; the synthesis-state colours fill in green as each sentence completes.

Changed

Audiobook casting — smarter speaker attribution: the LLM prompt now reasons about conversational turn-taking (in a two-person exchange speakers alternate, so untagged lines are attributed by context rather than dumped as “Unknown”), and each passage is given the recent dialogue from the previous one so a conversation continues correctly across passage boundaries. The deterministic fallback (used when the LLM is unavailable) also got a conservative two-person turn-taking fill and a stop-list that rejects common German non-name words (Sofort, Stimme, Frage, Plötzlich…), so it no longer invents bogus characters.
Character sheets — self-filling across the book: sheets now build up progressively — each passage receives the sheet-so-far (with which fields each character still needs) and the model fills gaps and refines instead of starting from scratch, so details accumulate as more of the book is read.
Read Aloud — library now lives on the server (syncs across devices): saved books, their synthesised audio, and reading position were previously stored only in the browser (IndexedDB), so a book saved on the laptop never appeared on the desktop. The library now persists under the server's config volume (reader_library/<id>/ with meta.json, the source document, and per-unit MP3s) via new /api/reader/docs… endpoints. Any device pointed at the same server sees the same "My books" shelf; opening a book is instant and its audio streams per chunk on demand (nothing is bulk-downloaded), and saves stay incremental (only new chunks upload).
Language switcher — replaced the sidebar language dropdown with a flag toggle next to the "Voice Creator" headline (click to switch interface language). Added German strings for Read Aloud ("Vorlesen") and its UI.

Performance

Read Aloud — memory & smoothness for long books: decoded audio (uncompressed PCM) is now kept only for a small window around the playhead and re-decoded from the cached MP3 on demand; off-screen PDF page canvases are released and re-rastered on return — together these bound memory on big books (previously both grew unbounded and could crash long sessions). The next chunk is pre-decoded during playback for gapless transitions, transport actions no longer scan every unit (single tracked "reading" index), PDF sentences/units are built incrementally per page (no end-of-parse spike), and library saves are incremental — only newly-synthesised chunks are written (a separate per-unit audio store), instead of rewriting the whole book each save.

Fixed

Audiobook casting — German (and other) quote styles not recognised: dialogue marked with German guillemets »…« / „…“ / ›…‹, French «…», curly “…”, CJK 「…」, or em-dash speech was treated as narration, so books like German novels cast everything to the narrator. The LLM prompt now explicitly handles all these styles (with guillemets called out), passages with no quotation marks skip the LLM entirely (so genuine narration isn't shown as a failure), PDF line-break hyphenation is mended (Schwer- tes → Schwertes) for clean speech, and if the LLM call fails on a passage that does contain quotes, a deterministic fallback splits out the dialogue and attributes speakers from speech tags (»…«, sagte Riskan → Riskan; pronouns rejected) so the book stays castable with real names even when the LLM is offline.
Read Aloud — auto-scroll: while reading, the view now scrolls only the document pane instead of the whole window, so the currently-spoken line no longer slides up under the app header out of view.
Read Aloud — backend dropdown stuck on "Checking…": the reader's TTS-backend select is now populated by the shared backend refresh and fetched on demand when the section opens, so it fills reliably even if backends finish loading after you're already on the tab.
Read Aloud — large PDFs froze the page ("this page is not responding"): the page-parse loop now yields to the browser periodically (with a "Reading PDF… page x / n" indicator), and per-sentence status overlays are created lazily per page instead of all at once. A 60-page book now imports with a max main-thread stall of ~40 ms (was multi-second), creating only the visible pages' overlays.
Chunked TTS — "Failed to fetch" on long text: splitTextIntoChunks only split on sentence terminators (.!?), so newline-delimited text (e.g. German bullet lists or care-plan notes) was never split — the full page was sent as one request, causing a TCP timeout that the browser surfaced as "Failed to fetch". Fixed by processing each line individually before applying the sentence regex. Also moved generation.js from deferred batch E into the main feature batch so generateChunkedTts is always defined before the user can click Generate.

[1.6.0] — 2026-06-03

Added

Script Rehearser — Cast overhaul: Card / List view toggle; sort & filter (name, gender, language, line count, tag); character-card-game styling (large portrait, name, description line, action row); per-character online voice picker (audition the match, browse alternatives, pick from your library, or search fish.audio inline); "Hear a line" button that synthesizes a representative one-liner from the character's own dialogue in their assigned voice.
AI character notes — Match local / Match online / Design all now research the play and drop a per-character note (description, gender, speaking style).
Rehearser import auto-save — uploading a script (PDF/text/FDX/Fountain) saves it to the Library immediately.
Internationalization (i18n) — interface language picker with German translation of the UI chrome; English is the source language (static/js/i18n.js, extend via I18N_DICT).
Progressive Web App — installable with offline app shell (manifest.webmanifest + network-first service worker), iOS web-app meta and safe-area support.
Test suite — Playwright smoke + functional tests (desktop and iPhone/WebKit profiles): app load, sections, clone tabs, PWA, rehearser parse→cast, bundle, i18n.
Build tooling — opt-in single minified bundle (npm run minify → static/dist/main.min.js, loaded when ?bundle=1); architecture & migration notes in docs/ARCHITECTURE.md.

Changed

Accessibility → WCAG 2.1 AA — accessible names on all controls, AA text/badge/button contrast, keyboard-focusable scroll regions (audited with axe-core; 40+ violations → a handful of edge cases).
Performance / mobile stability — GZip responses; content-visibility virtualization for long lists; lazy-loaded images; Rehearser caps decoded-PCM memory to a sliding window (fixes iPhone crashes); leaked AudioContext closed; bounded-concurrency bulk operations.
Clone a Voice — reworked GUI — integrated tab strip (Microphone · Upload · URL/YouTube), clearer sections, scroll-to + obvious "transcribing…" feedback, sample sentence keeps the typed name across language switches.
Fish-Speech tone — per-line tones now reach OpenAudio S2 via inline [tag] markers in the text (the instruct field is ignored by S2).
fish.audio import — de-duplicates voices already in the library and diversifies matches so different characters don't all get the same fallback voice.
Get Voices Online — tabbed, integrated source switcher; the scrape box lives only under "Direct sources".
Voice library — editable Voice ID (rename), complete country/accent list (decoupled from language), always-visible Select all toggle, redesigned bulk-delete confirmation modal.

Fixed

Screenplay parser — title-page text, numbered scene headings (A1 EXT. … EVENINGA1), OMITTED/CONTINUED markers and dated page slugs are no longer detected as characters.
Narrator & all voice pickers now list the full voice library (lazy-loaded if needed).
Cast list controls wire reliably regardless of when the section mounts; role names no longer truncate; avatars enlarged.

[1.5.0] — 2026-06-01

Added

Fish-Speech TTS backend — clones a voice's saved reference WAV (consistent identity) and honours inline emotion markers like (angry), (whispering), (excited) per line. The only backend that is both WAV-anchored and style-aware; the Rehearser prefers it when available. Configurable via FISHSPEECH_URL.
Fish.audio Voice Library browser (Get Voices Online) — search/filter the ~2M public voices at api.fish.audio, preview samples, and one-click Import (MP3 → WAV + reference transcript) → an instantly clonable voice.
Cast tab redesigned as character cards — big avatar, name, language, gender, tags, voice picker, voice-design prompt, "Character soul · LLM brief" with Develop (LLM), and per-character Ignore / Hide / Delete.
Bulk-edit lines on the Stage — a Select mode adds per-line checkboxes: Ignore, Hide, Delete, Un-ignore, Show-hidden.
Designed voices — display name is the character name, the script becomes a tag, and an auto-picked gender/type avatar icon replaces the language flag.
Clone a Voice — name-first flow — name first (drops into the read-aloud sentence), live voice-ID, auto-transcribe after trim, auto-save when ready, and a File / URL / Microphone source picker.

Changed

IMSDb scraper — resolves the real script via each title's detail-page "Read Script" link instead of guessing a slug.
Rehearser default backend — voice_clone (then fishspeech) for consistent identity; the tone-warning explains the trade-off both ways.
Try It Out — the cramped voice/backend row is now a clean responsive layout.

Fixed

Narrator was silent — narratorVoice now stays in sync with the narrator cast row.
About → Changelog was empty — CHANGELOG.md is now shipped in the image and resolved resiliently.

[1.4.0] — 2026-06-01

Added

IMSDb browser — list / cover view toggle — switch between poster-grid and compact list view; preference persisted in localStorage.
IMSDb browser — local catalogue cache — catalogue is cached in localStorage for 6 h (matching server cache), making reopening the browser instant.
IMSDb browser — title in fallback — script title shown on each gradient poster card while the real poster loads.
IMSDb browser — loading spinner — animated spinner while the catalogue fetches.
IMSDb browse button on Import / Export tab — the "Browse IMSDb" button is now also available on the Import / Export panel; modal moved to global scope.
Auto-design — detailed progress panel — each character shows an expandable card during voice design: gender chip, language, voice ID, age, and the full LLM-generated character description with a live spinner.
Auto-design — script title as voice tag — designed voices receive the script title as their tag value so they're easy to filter/find.
Auto-design — LLM endpoint datalist — the LLM endpoint field is now backed by a <datalist> auto-populated from all configured Language Models engines, plus hardcoded defaults (Ollama, vLLM, LM Studio, llama-swap, LiteLLM).
Stage — synthesis progress — the synth bar is now more prominent (gradient fill, spinner, sticky), each synthesising line pulses with a blue glow, and the page auto-scrolls to the active line.
Stage — tone warning banner — when a non-style-aware backend (voice_clone, streaming, NVIDIA) is selected and tone is set on lines, a dismissable amber warning banner names the backend and suggests a style-aware alternative.
Bulk-edit tools — new sticky toolbar in My Voices: select any number of voices with checkboxes, then: Set tag, Hide, Unhide, Rate, or Delete in one action.
Rehearser — Voice Design default — the TTS backend picker in Cast now defaults to voice_design (style-aware) instead of voice_clone, so tone selections work out of the box.

Changed

Stage — edit button moved to right gutter — the pencil (edit text) button is now stacked with the note button in the right-side gutter of each dialog block, keeping the block header clean.
Tone / instruct order — when an emotion is set on a line, the instruction now leads with a directive ("Speak in a <emotion> manner. <voice profile>") so the model prioritises the tone over the base identity description.
My Voices — hidden voices in sub-tabs — fixed: Cloned, Designed, and Favorites tabs now respect the "Disabled" checkbox filter; hidden voices no longer appear unless explicitly requested.

Fixed

IMSDb covers showing as flat lines — replaced aspect-ratio on a flex child (unreliable in all major browsers) with the padding-bottom: 150% wrapper trick, guaranteeing a correct 2:3 poster ratio.
Rehearser TTS backend "No backend available" — refreshRehBackends now triggers the global backend probe if _ttsBackends is empty, and registers a _ttsRefreshHook so the select stays in sync with the Engines page.

[1.3.0] — 2026-05-31

Added

Live mic monitor in Clone a Voice — level-meter and scrolling oscilloscope waveform in the Microphone card. "Check level" / "Stop monitor" buttons, mic gain slider. Recording uses raw mic constraints (no echo-cancel / AGC).
STT engine picker in Clone → Transcript — pick any configured STT backend when auto-transcribing, bypassing an unavailable Whisper.
Better sample texts — all 8 languages rewritten to ~38 words / ~15 s, phonetically rich, proper Unicode diacritics.

Fixed

Empty "Read aloud" field — sample text now reliably populates on load and when navigating to the Clone section.
Recording quality — MediaRecorder requests 256 kbps in Clone and STT→TTS.
OGG file import — explicit extension list in accept=.

1.2.0 — 2026-05-29

Added

Remember last section on reload — the active section (and Settings / Engines sub-page) is persisted in localStorage. A hard-reload (Ctrl+Shift+R) now returns to the same page instead of always jumping to My Voices.
Conversation: live speech preview — while recording, the active Whisper STT backend transcribes accumulated audio every 2.5 s and shows the result in the text input field in real time. The input is pre-populated with this live guess before the final Whisper result arrives. Also tries the browser's Web Speech API first (works on HTTPS / localhost) for even faster results.
Conversation: Voice Activity Detection (VAD) — recording now auto-stops after 1.5 s of silence detected via the Web Audio AnalyserNode RMS level. A "Sending in X.Xs" countdown appears in the status bar so the timing is visible. An Auto-stop toggle in the input bar lets users disable VAD and revert to click-to-stop. A thin audio-level bar below the status line shows microphone volume in real time during recording.
Conversation: hands-free mode — after the agent finishes speaking, the microphone restarts automatically. A Hands-free toggle (on by default) disables this; clicking the mic button manually always cancels any pending auto-restart.
scripts/release.py — automates version bump + CHANGELOG promotion. python scripts/release.py --patch|--minor|--major [--dry-run] renames [Unreleased] to the new version, updates compare links, writes VERSION, commits, and creates an annotated git tag in one command.
Git pre-commit hook (scripts/hooks/pre-commit) — warns (does not block) when .py/.js/.css/.html files are staged but CHANGELOG.md or VERSION are not. Run bash scripts/install-hooks.sh after cloning.
scripts/install-hooks.sh — one-liner to install the hook after a fresh clone: bash scripts/install-hooks.sh.

Changed

Config and logs are now bind-mounted local folders — replaced the opaque named Docker volume with ./config/ and ./logs/ host directories. portainer-stack.yml updated with absolute host paths.
Server writes a rotating log file — RotatingFileHandler writes INFO-level and above to ./logs/app.log (rotates at 5 MB, 3 backups).

Performance

Skeleton loading view — index.html shows an animated shimmer placeholder immediately on first paint; fades out once JS finishes loading.
Self-hosted WaveSurfer and MDI icon font — removed render-blocking CDN requests; assets now served locally from static/vendor/.
Parallel JS module loading — restructured loader.js into 4 ordered batches; round-trips reduced from 17 to 6, 9 files fetched simultaneously.
Version-based JS/CSS cache busting — versioned assets served with max-age=31536000, immutable; bumping version invalidates the cache.

Fixed

LLM returned empty response (Qwen3 thinking mode) — conversation turn now falls back to reasoning_content for think-only responses; error message hints to add /no-think to the system prompt.
Engine settings lost after container recreate — container names and URL overrides now persisted as server settings (engine_container_names, engine_local_urls); restored from server on first page load.
Text-input turns returned 422 — changed audio form field to Optional[UploadFile] = None so text-only turns don't require audio.
Conversation input bar hidden when mic unavailable — warning box moved inside conv-chat-window so it never pushes the input bar off-screen.
Browser caches old section HTML — loader.js appends ?v=<timestamp> to every section fetch.
Various import errors and container restart issues fixed.

1.1.0 — 2026-05-29

Security

Fixed path traversal in /api/browse-dirs — Added a _BROWSE_BLOCKED blocklist (/proc, /sys, /dev, /run, /boot). Requests for paths under these directories now return HTTP 403 instead of listing kernel/system files.
Hardened yt-dlp output path — After a YouTube download completes, the resolved output path is verified to be inside TEMP_DIR via .relative_to(). A file written outside the temp directory is rejected with an SSE error event and never registered.
Removed CORS wildcard on /api/proxy-audio — Access-Control-Allow-Origin: * was unnecessary (all callers are same-origin) and exposed proxied audio to arbitrary cross-origin requests. Header removed.
Temp file registry now enforces a TTL — _registry changed to dict[str, tuple[Path, float]]. _registry_gc() evicts entries older than TEMP_FILE_TTL_SECONDS (default 2 h, configurable via env var) and unlinks their files, preventing unbounded disk growth on long-running instances.

Performance

Settings and routing rules cached in memory — _load_settings() and _load_tts_routes() previously read from disk on every API request (55+ calls per TTS synthesis). Both now use mtime-checked in-memory caches that invalidate automatically on write, eliminating redundant file I/O.

Added

Version number — VERSION file at repo root; read by core/constants.__version__ and surfaced via GET /api/version. Displayed as v1.1.0 in Settings → About.
Text input in Conversation Playground — a pill-shaped text field and send button (→) sit left of the mic button. Pressing Enter or → sends text directly through the LLM → TTS pipeline, skipping STT entirely. Makes the playground fully usable without a microphone (HTTP context, no mic permission, remote access). The backend /api/conversation/turn now accepts an optional text form field; when set, the STT step is skipped and the STT latency row shows —.
Container name field on all engine cards — every TTS and STT engine card (Docker stack cards and static "Other Local" cards) now always shows the Docker container name input row. Previously absent/not-installed cards hid it; now it is always visible so the container can be pre-configured before starting.
Connect / Disconnect toggle — the Connect button now shows "Disconnect" (green, check-network icon) when already connected and toggles back on click. State persists in localStorage.
Auto-apply on Connect — a successful connection probe automatically saves the URL to Settings and makes the backend available in TTS/STT dropdown menus immediately, without requiring a separate "Use as TTS/STT" click.

Changed

Connect button redesigned — moved out of the URL input row into a dedicated dc-controls-row. Restyled as a solid blue primary CTA (was a small teal outline button). Shows a spinner icon while probing.
"Use as TTS / STT" button — larger padding, bolder teal border, chevron icon, tooltip explaining it sets the URL in Settings. Gains .active highlight once applied.
Unified controls row on every engine card — consistent left-to-right order: [Connect/Disconnect] [Stop | Start | Restart] [Use as →]. Docker action buttons hidden until a container name is entered; Use-as button right-aligned.
initStaticDockerManagement — rebuilt to use the same dc-controls-row structure as the dynamic Docker stack cards. The existing .llm-local-ping button is moved from inside the URL row into the controls row at initialisation time.

Backend refactor — server.py (5 560 lines → 43 lines) — all logic extracted into single-responsibility modules:

Dockerfile updated with COPY core/ core/ and COPY routes/ routes/. docker-compose.yml updated with ./core:/app/core:ro and ./routes:/app/routes:ro.

Frontend refactor — app.js (8 744 lines → 16 modules) — split into static/js/ with loader.js loading them sequentially in dependency order:

Fixed

chrome://flags/… URL unreadable in mic-blocked warning — the global code { background: var(--panel) } rule caused the URL text to render as white-on-light-grey inside the red warning box. Fixed with inline styles (background: rgba(0,0,0,.35); color: #fff) on the <code> element, plus a Copy button so users don't need to manually select invisible text.

1.0.0 — 2026-05-28

Initial feature-complete release.

STT backends — OpenAI Whisper (port 8010), faster-whisper-server, whisper.cpp, Groq Whisper (cloud, free tier), NVIDIA Parakeet ASR. Real transcription probe in health check (not just TCP reachability).
App Routing — per-app / per-voice / per-language TTS routing rules with automatic language detection and optional before/after sound effects.
Conversation Playground — full STT → LLM → TTS pipeline with real-time SSE streaming, latency stats panel (STT / LLM TTFT / LLM total / TTS / Total), turn history, system prompt, and insecure-context warning.
Engines section — LLM / STT / TTS sub-pages; Docker container management (Start / Stop / Restart via Docker socket); custom engine cards; ElevenLabs voice library browser.
Performance Benchmark — single-voice and batch benchmark with RTF tracking, sparkline trend, and persistent history.
Audio effects — reverb, chorus, delay, compressor, gain, pitch shift (via pedalboard).
