 ## Changelog
 
-### v6.15.1 — 2026-10-12
-
-- **Docs:** German sample files (10 voices, 0.6B-Base streaming, same text) in `samples/german sample files/` with an `index.html` that has an audio player per voice (open locally or via GitHub Pages) and a link table, added for the German-pronunciation question in the forum.
-- **Docs:** image tag table now lists `v6.15.0`; the `v6.15.0` images and the `:v6`/`:latest` aliases are on Docker Hub.
-- **Image:** unchanged (`:v6.15.0`), no rebuild needed.
-- **Rollback:** `git checkout v6.15.0` (documentation only).

 ### v6.15.0 — 2026-10-11
 
 - **Perf (opt-in):** `TTS_COMPILE_PREDICTOR=1` compiles the 15-step code-predictor loop with `torch.compile` (Inductor/Triton) before CUDA-graph capture. Profiling showed the predictor needs ~5350 kernels per frame (about 54 % of the decode time); fusing them cuts its replay from ~23 ms to ~17.5 ms. Measured through the API on GB10 with the 0.6B-Base streaming server (same voice and text, other TTS containers stopped): 1.6–1.7x -> 1.8x real-time on long text, first audio ~670 ms -> ~550 ms. Listening comparison of 5 voices: no audible difference. Costs about one extra minute at startup. Default is off (unchanged behaviour).
-- **Image:** rebuilt as `v6.15.0` / `v6.15.0-streaming` (adds `patches/predictor_compile.patch`) and pushed to Docker Hub together with the `:v6`, `:latest`, `:v6-streaming` and `:latest-streaming` aliases.
+- **Image:** rebuilt as `v6.15.0` / `v6.15.0-streaming` (adds `patches/predictor_compile.patch`). Built locally; not yet pushed to Docker Hub, so the tag table above still lists `v6.13.1` until it is.
 - **Investigation notes:** memory pressure/swap, GPU clocks, CPU core type and `chunk_size` do not limit throughput; `float16` fails (inf/NaN logits, device-side assert); flash-attn is irrelevant for single-token decode. F5-TTS, EmoKnob and Breeze-TTS-2 were benchmarked against Qwen3-TTS: slower than real-time (Breeze 0.5x, EmoKnob 0.1x) or without streaming/German (F5 ~5x) and not usable quality-wise in our test.
 - **Rollback:** unset `TTS_COMPILE_PREDICTOR` (or use the `:v6.13.1` image).
