- Punctuation & Backspace Input Freeze : Resolved a severe UI freeze / ANR when typing punctuation (such as colons `:`) or backspacing by optimizing dictionary blacklist evaluation with instant O(1) hash lookups and lazy candidate scoring.
- Android 12 Crash Loop on Keypress: Resolved a fatal `NoSuchMethodError` crash loop on Android 12 (API 31/32) caused by `VibrationAttributes.createForUsage` (introduced in API 33), restoring smooth typing on affected devices.
- Vibration Intensity Slider: Restored vibration amplitude scaling when custom intensity is set, resolving an issue where the haptic slider only operated at full intensity or off on certain devices.
- Crash Log Reporting in Release Builds: Hardened crash report generation to use reliable internal storage and exposed internal crash reports in settings dialogs across release builds.

- Auto-Capitalization Toolbar Controls & JSON Actions: Added optional toolbar buttons, pinned controls, and custom JSON layout key mappings for toggling auto-capitalization and force auto-capitalization, with real-time state refresh and accessible screen reader descriptions.
- Comprehensive Global Translations: Reached 100% complete translation coverage across 25 target languages and regional variants for all recent settings and UI strings.
