What's New
Fixes critical crash on graph divergence and optimizes graph loading speed.
New Features
- New public APIs for graph serialization (Graph_EncodingVersion and Graph_GetDecoder)
Improvements
- Incremental matrix rebuilding for faster graph loading
Bug Fixes
- Fix replica SIGSEGV on graph divergence
Upgrade Notes
External modules using graph serialization should adopt the new public APIs Graph_EncodingVersion and Graph_GetDecoder for future compatibility. No breaking changes exist for existing graph operations, but the improved loading performance may affect resource usage during startup.
