About Synapse
Synapse keeps grinding: steady MSC feature work while the event core migrates to Rust
Synapse is element-hq's reference Matrix homeserver. Recent releases are a steady biweekly cadence of MSC spec features, federation and sync bugfixes, and a methodical port of the event core from Python to Rust. This is a mature project in maintenance-and-optimization mode, not one chasing new product surface.
