✨ New Features

Multi-language romanization (MultiLangRomanizer)

• Added detection for 5 new scripts: isThai(), isArabic(), isGreek(), isHebrew(), isVietnamese() — enables automatic language identification for AI translation prompts
• Added romanizeVietnamese(): NFKD-decomposes and strips diacritics to plain ASCII Latin (e.g., "Việt Nam" → "Viet Nam")
• Cyrillic romanization: Now actively routed in LyricsRepositoryImpl for all songs with Cyrillic text
• AI translation enhancement: AiStateHolder.detectLyricsLanguage() identifies the source language before sending translation requests, prefixing prompts with detected language for better AI results

New app languages

• Japanese: Full translation (values-ja/) — 10 string files across all categories
• Vietnamese (values-vi/) and Traditional Chinese (values-zh-rTW/): Complete translation resource sets
• Added missing translations: German changelogs/settings, Korean/Norwegian/Russian changelogs/settings
• Locale config: locales_config.xml now registers all 14 supported locales for Android 13+ language picker

Note: I only touched my own languages aside from the new additions.

LYRICS settings category

• New dedicated LYRICS category in Settings between APPEARANCE and PLAYBACK
• Moves lyrics source priority (embedded/online/local) and immersive lyrics display settings into their own section
• Distinct color scheme in the settings category grid

🐛 Bug Fixes

Lint errors (21 resolved)

Type	Count	Fix
MissingDefaultResource	14	Created base values/plurals.xml with English defaults for all Arabic-only plural names
NewApi	3	Annotated BlurEffectCache with @RequiresApi(31); guarded ForegroundServiceStartNotAllowedException with SDK check
WrongConstant	1	Suppressed lint on takePersistableUriPermission flags
NonObservableLocale	2	Suppressed lint on Locale.getDefault() in composable functions
MissingIntentFilterForMediaSearch	1	Added MEDIA_PLAY_FROM_SEARCH intent-filter to MainActivity for Android Auto voice search

Lyrics loading priority

• Fixed loading order in LyricsStateHolder: local files → embedded metadata → stored database lyrics (was incorrectly prioritizing stored lyrics over local sources)

AI max tokens

• Increased default from 4096 → 8192 for longer AI responses
• Fixed redundant resetLyricsSearchState() call when opening the lyrics sheet

---

🔧 CI & Build

• Added --no-build-cache to all Gradle build steps in CI workflows for reproducible builds
• Reordered CodeQL workflow: Kotlin version pinning now happens before Gradle setup
• Removed explicit maxHeapSize from app/build.gradle.kts
• Cleaned up version overrides in gradle/libs.versions.toml

---

🛡️ Security & Utility

• ServerUrlUtils.kt: Server URL validation utility to prevent SSRF/malformed URLs in Jellyfin, Navidrome, and GDrive configurations
• app/lint.xml: Lint baseline configuration to manage known issues

AI Errors arise after extended periods of time?
Investigating currently.

Results: Incapable of doing repair work at this time due to many at-home items occuring, including my Aunt's new baby!

Since I will be assisting with this child as she is a single mother, I have to relay my time to items of immediate concern, this includes my own physical health and similar items.

You may leave comments and or reviews on problematic items for me to see, I will review and correct any where possible as soon as I am available.

Just fixed most to all AI errors in #2497, your changes should work now!

Any suggestions welcome, thanks! :)

Actually, those issues were noticed during normal usage after an extended period of time.

About three days later it started working, but the entire prompt response from the ai was being output where the lyrics go, including formatting markers like ** and similar. It was also being aggressively cut-off due to what looked like token or length limiting.

[VoidX3D]

Oh then it should already fixed in the xml conversion for the new ai response handeler and token limiter. I have created a new class type promt for the ai lyrics so using that should resolve most of the issued you can analyze my code and update your lyrics part with it it should reslove all issues.

[VoidX3D]

For the token system i have added a new Generation Parameters to combat the same issues for the other playlists where the responses was cut in half due to restraints
