What changed from v7.0.1 → v4.20.4?What's new in v2.14.6 after v4.20.4?

AI Summary

This release focuses on improving replica stability and performance during graph loading. It fixes crashes during divergence, removes full sync overhead during decoding, and exposes new public APIs for graph serialization.

Key Highlights

Fixed replica SIGSEGV on UPDATE_EDGE/UPDATE_NODE divergence by triggering a full resync instead of crashing.
Improved graph loading performance by removing full sync from the decoder and using incremental delta-matrix rebuilding.
Added new public APIs `Graph_EncodingVersion` and `Graph_GetDecoder` for external modules.

New Features

Export `Graph_EncodingVersion` and `Graph_GetDecoder` APIs

Full Release Notes

## What's Changed

### Bug Fixes
* fix(effects): stop replica SIGSEGV on UPDATE_EDGE/UPDATE_NODE divergence - replicas no longer crash when an effect references a node or edge that no longer exists locally; the mismatch is now detected and triggers a full resync instead (#2581)

### Performance
* remove full sync from decoder - transpose matrices are rebuilt incrementally as delta-matrix components are set during RDB decoding instead of forcing a full sync at the end, speeding up loading of persisted graphs (#2584)

### Improvements
* serializers: export Graph_EncodingVersion and Graph_GetDecoder - new public APIs let external modules (e.g. graph-offloading) stamp dumps with their encoding version and select the matching decoder on load (#2552)
