About Synapse
Synapse holds its biweekly cadence, grinding through Matrix spec MSCs
Synapse is the reference Matrix homeserver, shipping on a steady two-week release train. Recent work centers on Simplified Sliding Sync (MSC4186), sticky events, cancellable delayed events, and a preview-URL capabilities API, alongside a run of federation and to-device stability fixes. This is maintenance-heavy engineering: paired rc/stable releases, a mid-May CVE security patch in 1.152.1, and Debian 12 packaging now being retired.
