v1.5.4

• The add-on icon is shown again on the player menu row for the regular player and Shorts; the 1.5.3 resource rewrite had dropped it.

v1.5.3

• Smaller and simpler: the code was hand-rewritten module by module (dead code removed, long logic split, about 8-12% less main code) and the extension is shrunk by R8; the patch package drops from 1.3 MB to about 0.57 MB. Translation prompts and protocol are unchanged and match the pinned upstream.
• Experimental support for YouTube 21.40.161, 21.39.522, 21.38.130, 21.28.208 and 21.23.492, following the experimental targets of official Morphe Patches 1.47.0. 21.13.164 and 21.07.247 are no longer declared.
• Both patches are selected by default. The reference caption cache now persists, saving one download when reopening a video.

v1.5.2

• Keep uploaded subtitles exactly as authored, including two-row subtitles such as romanization above a translation; only auto-generated subtitles get locally optimized sentence breaks and page turns, tuned for Japanese and other unpunctuated languages.
• Remove bracketed furigana readings from the text sent for translation, so the translation does not repeat them.

v1.5.1

• Fix captions that were missing or shown twice on videos whose subtitle tracks repeat every cue.
• Choose the source subtitle track by the video's spoken language, preferring human-made tracks.
• Show the video's own subtitles in the selected language directly, without translation requests, with sentence breaks and page turns optimized locally.

v1.5.0

• Support YouTube 21.20.405 with official Morphe Patches 1.47.0.
• Fix Shorts captions disappearing after looping or reopening a video.
• Fix YouTube crashes caused by interrupted translation responses.
• Improve caption pagination and prevent repeated pages and flicker.
• Reduce caption startup latency with streaming responses and faster planning.
• Display original subtitles in the AI caption overlay without translation requests.

v1.4.1

• Remove prompt settings.
• Fix Arabic interface layout issues.

v1.3.5

Fixes

• Caption font size now spans 8–15 sp, with 13 sp as the default. The slider, saved setting, and localized hints agree.
• Saved diagnostic filenames and export manifests show the release version, 1.3.5. The engine identifier remains event-rebuild-r2.12.

Source and verification

This release is patched from the supplied 1.4.0-local.2.12 MPP. A nearby R2.12 Java source snapshot and the exact assembleable Smali source are included in the repository. The Smali source is authoritative for the released engine; see source recovery and rebuild notes.

The MPP has the same 72 entries as the supplied bundle. The only changed contents are the version manifest, 14 locale size hints, and the two DEX files. Disassembly shows five intentionally edited extension classes and one patch class; all other classes match. The Java test suite passed 330 tests, and the bundle and metadata validators passed.
