browser-use/video-usev4.20.4Aug 20, 2026by swilly22

AI Summary

A release focused on stability improvements, specifically fixing replica crashes during divergence, and performance optimizations for graph loading and serialization.

Key Highlights

Fixed replica SIGSEGV crashes when encountering diverged nodes or edges during updates.
Improved graph loading performance by removing full sync from the decoder.
Added public APIs for external modules to manage graph serialization versions.

New Features

Export Graph_EncodingVersion and Graph_GetDecoder for external modules

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)
