+## 🚀 What's New
+
+### 👆 Gesture & Swipe Engine (Pure-Java)
+*   **OutOfMemoryError Fixes**: Fixed OOM crashes during gesture typing. Optimized dictionary word streaming and coordinate layout packing to dramatically reduce heap allocations and GC pressure.
+*   **Blacklist Filtering**: Prevented blocked and blacklisted words from appearing in gesture suggestions or history.
+
+### 📖 Dictionary & Typing Predictions
+*   **Privacy Improvements**: Blocked/blacklisted words are now prevented from entering user history and next-word suggestions cache.
+
+### 🛠️ Input & Settings Customizations
+*   **Auto-Correction Triggers**: Added a new setting toggle to choose what triggers auto-correction: Spacebar only, Punctuation only, or both.
+*   **Cursor Selection Fix**: Fixed text selection bug where moving the cursor under automatic shift mode (auto-capitalization at the start of a sentence) caused text selection.
