🚀 LeanType 4.3.1-beta2

🐛 Fixed

• Dictionary Traverse Session Concurrency (SIGSEGV Fix) (#759): Synchronized native traverse session access during word suggestions in BinaryDictionary to prevent concurrent traversal race conditions and fatal native segmentation faults (SIGSEGV).
• Samsung & Multi-Profile IME Crash Resolution: Prevented fatal RuntimeException on Samsung devices (such as Galaxy S25 Ultra) and isolated environments (Knox, Secure Folder, Work Profiles, Direct Boot) where system inputMethodList excludes third-party IMEs, by replacing rigid equality checks with direct package matching and resilient PackageManager fallbacks.
• Multilingual History Isolation & Learning (#763): Isolated learned and unlearned words to matching language dictionaries in multilingual setups instead of commingling vocabulary across unrelated language histories.
• Multilingual Locale Priority Order (#762): Preserved primary locale dictionary lookup order using a linked set, ensuring main language suggestions take precedence during multilingual typing.
• Android 7.1.2 Compatibility Crash (#756): Avoided ThreadLocal.withInitial in Thai word break iterator to prevent fatal crashes on Android 7.1.2 (API 25) and below.
• InputConnection IPC Hardening & Memory Leak Prevention: Hardened RichInputConnection against dead-process and remote app IPC crashes, safely closed unclosed dictionary and asset input streams, and eliminated memory leak vectors.
• Dynamic Dictionary Download & Deletion Reloads (#761): Broadcast dictionary update intents upon downloading or deleting user dictionaries, ensuring the keyboard engine immediately refreshes active wordlists without requiring a restart.
• Transient Shift State Reset on Input Restarts: Cleared one-shot shift state on input restarts and text field switches to prevent inadvertent capitalization, while strictly preserving Caps Lock.
• NULL Input Type Auto-Capitalization Guard: Guarded TYPE_NULL input fields and invalid editor selections (initialSelStart == -1 && initialSelEnd == -1) from receiving auto-capitalization flags.
• Synchronous Blacklist Enforcement: Synchronously loads and reloads the blocked words blacklist to eliminate race conditions where blocked words could temporarily appear in suggestions, and resolved deletion persistence issues.
• Autocorrect Default Threshold Preset Alignment (#760): Corrected default auto-correction threshold configuration to properly align with the Balanced preset.
• N-Gram Context Hash Collision Fix: Corrected hash collisions in NgramContext to ensure accurate next-word context lookups across multi-word prediction pipelines.
• Missing Settings Menus & Sound Search Indexing: Restored missing preference options across Text Correction, Toolbar, Gesture Typing, and Sound screens, and corrected sound settings indexing in search.

✨ Added

• Clear Learned Words & User History: Added a dedicated option in Text Correction / Suggestions settings to reset learned words, personalized dictionary history, and session word boost caches.
• Irish & Group 1 Latin Input Subtypes: Added input subtypes in method.xml for Irish (ga, ga_IE), Bosnian (bs, bs_BA), Norwegian Nynorsk (nn, nn_NO), Cebuano (ceb), Malagasy (mg), Sardinian (sc), and Toki Pona (tok).

⚡ Performance

• Draw-Loop IPC Elimination & Zero Key Allocations: Removed Binder IPC queries from active keyboard canvas draw routines, eliminated temporary object allocations per key draw, and optimized gesture trail invalidation for smooth 60fps rendering.

🧹 Maintenance & Tests

• Plugin Update Deduplication & Packaging: Consolidated plugin update checks into a centralized PluginUpdateHelper and hardened build scripts for F-Droid reproducibility.
• Resource & Build Hygiene: Pruned orphaned translation strings, removed redundant ProGuard rules, and removed unused legacy split keyboard configuration references (#751).
• Shift State Unit Test Suite: Added dedicated unit tests in KeyboardStateShiftTest covering shift state clearing and caps lock persistence across input restarts.
