🚀 What's New in v4.0.1
🛠️ Bug Fixes & Stability Improvements
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.

Note
Its beta3 even though it says beta2 ,
Also the version code accidently changed to 4001 on beta2, the stable version would be 4000 so if you can't downgrade you might need to backup and restore
If there is no crash reported, ill release the v4.0.0 stable today itself, since other users still downloading buggy v3.9.9
🚀 What's New
🛠️ Bug Fixes & Stability

🚀 What's New
🛠️ Crashes & ANR Fixes
Native JNI SIGABRT Fix: Fixed a native crash in the LatinIME keyboard library (libjni_latinime.so) caused by thread-unsafe memory access during dictionary word iteration.
Gesture Indexer ANR Fix: Prevented keyboard freezes and Application Not Responding (ANR) errors by running the fallback Java gesture indexer asynchronously on a background thread instead of blocking the main thread.
Asynchronous Dictionary Cleanup: Moved dictionary closing and cleanup to a background coroutine to prevent the main thread from blocking on JNI write locks when switching languages.
📖 Dictionary Preservation on Upgrade
Manual Import Preservation: Stopped the app from deleting manually imported or replaced custom dictionaries during version upgrades.
