-### Refactored -- **Removed Java Gesture Engine**: Completely removed the experimental Java gesture engine in favor of the native C++ gesture engine, preventing crashes and reducing codebase bloat. - -### Fixed -- **Native Gesture Library Safety**: Strictly validated native gesture library compatibility in JNI loader to prevent `SIGSEGV` native crashes with incompatible libraries. -- **IME Lifecycle & ANR Prevention**: Cancelled gesture indexing tasks and made dictionary cleanup non-blocking on `LatinIME.onDestroy()`. -- **Background Service & Observer Leaks**: Unified background service toggles (Contacts, Apps, SMS OTP) and safely unregistered `ContentObserver`s on teardown. -- **Android 14+ System Fixes**: Exported ringer mode broadcast receiver and supported `onBackInvokedCallback` system behavior. -- **Personal Dictionary Fallback**: Gated personal dictionary unigram fallbacks behind `mPrioritizePersonalSuggestions` and disabled history dictionary unigram fallbacks. - -## [v4.0.1] - 2026-07-19 - -### Fixed -- **PointerTracker TimerProxy Safety**: Fixed `NullPointerException` on `TimerProxy.startTypingStateTimer` by defensively defaulting static `sTimerProxy` to `TimerProxy.NULL` and guarding accesses when proxy map references are cleared during view teardowns or transitions. -- **Dynamic InputConnection & Long Press Fix**: Fixed issue where re-opening the keyboard in Launcher or search fields dropped character input and long-press popup key selections by dynamically fetching the live system `InputConnection`. -

-### Fixed -- **Native JNI Protection**: Added `isValidDictionary()` guards and exception handling around `BinaryDictionary` JNI calls. -- **ANR & Freeze Prevention**: Added non-blocking timeouts to `CountDownLatch.await()` across backup/restore and file lookup paths. -- **Gesture Index Thread Storm**: Switched gesture index building to managed `KEYBOARD` executor pool. -- **Memory & View Leak Fixes**: Cleared static proxy references in `PointerTracker.clearOldViewData()`, enabled `largeHeap`, and trimmed memory when UI hidden. -- **Screenshot Scanner Optimization**: Replaced active background `ContentObserver` with on-demand check. -- **Regional Dictionary Fallback**: Aggregated main/emoji dictionaries across variant and language fallbacks (`en-IN` -> `en`). -- **Emoji Dictionary Persistence**: Fixed recognition of downloaded `emoji_*.dict` files and added preference tracking to prevent deletion on upgrade. -- **Thai Word Segmentation**: Preserved Thai word boundaries during text expansion. -
