About Synapse

Synapse maintains its reliable biweekly release cadence with stable v1.159 and v1.160 following a multi-fix security release in v1.157.2.

Synapse (Matrix homeserver, maintained by Element) follows a disciplined release cadence: RC1 → RC2 → stable, cycling approximately every two weeks. The most operationally significant recent event was v1.157.2 — a dedicated security release patching four high-severity and multiple moderate/low-severity vulnerabilities, with explicit guidance for open-federation homeservers to upgrade promptly. Subsequent v1.158–v1.160 releases continue the regular cadence; changelogs are externally hosted on GitHub.
