About Synapse
Synapse grinds through Matrix-spec MSCs while porting core event handling to Rust
Synapse, Element's reference Matrix homeserver, is in mature maintenance mode: each release blends experimental MSC support (Simplified Sliding Sync, Sticky Events, room-summary API), federation and sync bugfixes, and an ongoing port of core event handling from Python to Rust. Cadence is a stable release plus release candidates every couple of weeks. A May security release (1.152.1) patched two CVEs, including a worker-lock denial-of-service.
