Stoat vs Synapse: at a glance
What is Stoat?
Stoat moves to release candidates and Gerrit, and gives server admins more control.
Stoat's 0.16.0 release candidates add server controls: invites with expiry and use limits, permission to block external emojis, and bot roles that grant permissions when a bot joins. The team is also piloting Gerrit as its main source control and will now ship release candidates and backports.
What is Synapse?
Synapse 1.164 advertises Matrix v1.16 and v1.17 amid a run of dependency security patches
Synapse keeps its two-to-three-week cycle of candidates and stables. 1.164.0 went stable on 27 October with support for Matrix v1.16 and v1.17 and a dedicated endpoint for scheduling delayed events (MSC4140). The surrounding releases are security dependency bumps: certifi, a rustls-webpki update that distrusts the compromised eMudhra intermediate CAs, Pillow 13.0.0 for critical image-handling flaws, and msgpack against memory exhaustion on the public room list.
Stoat vs Synapse: editorial side-by-side
Stoat
5.0COMMS
Stoat moves to release candidates and Gerrit, and gives server admins more control.
◆ Current state
Stoat's 0.16.0 release candidates add server controls: invites with expiry and use limits, permission to block external emojis, and bot roles that grant permissions when a bot joins. The team is also piloting Gerrit as its main source control and will now ship release candidates and backports.
◆ Where it's heading
The feature list is about moderation and bot management for server owners, and rc.1 adds OpenTelemetry tracing for the file service. The process change toward RCs and backports suggests the team wants steadier releases for self-hosters.
◆ Prediction
A final 0.16.0 should follow the two RCs; the entries do not say when.
Synapse
5.0COMMS
Synapse 1.164 advertises Matrix v1.16 and v1.17 amid a run of dependency security patches
◆ Current state
Synapse keeps its two-to-three-week cycle of candidates and stables. 1.164.0 went stable on 27 October with support for Matrix v1.16 and v1.17 and a dedicated endpoint for scheduling delayed events (MSC4140). The surrounding releases are security dependency bumps: certifi, a rustls-webpki update that distrusts the compromised eMudhra intermediate CAs, Pillow 13.0.0 for critical image-handling flaws, and msgpack against memory exhaustion on the public room list.
◆ Where it's heading
The homeserver tracks the spec closely, stabilising MSCs as they land in Matrix releases, while backporting each security bump to the previous stable line. Sticky Events and User Status work suggest continued alignment with newer client features.
◆ Prediction
1.165 release candidates should follow within about two weeks, likely with further MSC stabilisations.
