Main modifications: (1) Version Additions

• Web Platform: Added support for a multi-threaded version.

(2) Interface Changes

• Android and iOS Platforms: Added interfaces to set and read alpha values for PAGLayer.
• HarmonyOS Platform： Added ComponentV2 support for PAGView and PAGImageView.

(3) Performance Optimization Upgraded tgfx to version 2.1.1, achieving significant performance improvements: 10x faster for basic graphics rendering (e.g., Rect) and 20x faster for text rendering.

Key Optimizations:

• Switched to a lock-free queue, enabling unlimited task scheduling.
• Added text atlas rendering and fast bounds estimation capabilities to improve text rendering performance.
• Fully adopted SIMD instructions for faster mathematical computations.
• Refactored the entire rendering pipeline to determine mergeability early, avoiding frequent creation and destruction of rendering objects.
• Introduced memory pool optimization to centralize memory allocation for temporary objects, reducing heap memory overhead.
• Automatic downgrade caching for ultra-large images (e.g., 4K) was added to reduce memory usage.

(4) Package Size Optimization

• Web Platform: Removed ASYNCIFY compilation parameter, reducing package size by 25%. Replaced the Web Worker version with a native pthread multi-threaded version.
• HarmonyOS Platform： Retain only pag-related symbols in the .so file.

(5) Feature Improvements and Stability Enhancements

• Web Platform: Refactored frame rendering logic to handle video decoding asynchronously.
• Web Platform: Fixed incorrect PAGLayer type issue when RTTI is disabled.
• Web Platform: Fixed errors when calling replaceImage and other interfaces.
• Web Platform: Fixed the issue where readPixels returned empty results.
• Web Platform：Fix web video decoding stuttering and improve React import compatibility.
• HarmonyOS Platform：Fixed memory leak issues.
• Fixed the incorrect scaling mode issue caused by File::editableImages being nullptr when all image layers are editable.
