+## [1.26.8] — 2026-09-09
+
+### Added
+- **Automatic Vision Layout Interpretation.** Magazine ingestion can now use a dedicated vision-language model after
+  Unlimited-OCR. It receives the original page and all positioned OCR candidates together to identify article
+  headlines, bylines, columns, paragraphs, sidebars, sources/footers, folios, ads, images, charts, statistics,
+  tables, captions and code before article/chapter creation.
+- **Explicit Review Classifications.** The exceptional manual-review workflow can add a headline, page number,
+  source/footer, or advertisement directly. Non-narratable types stay out of audiobook text by design.
+
+### Changed
+- **Magazine Parsing Preserves Whole-Page Context.** The semantic pass now keeps up to 120 regions from a page in
+  one request, rather than splitting normal complex pages into contextless groups of 60.
+- **Richer Layout Labels.** Sources, citations, footnotes, infographics, statistics and adverts are mapped to their
+  semantic types instead of falling back to generic article body text.
