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.
A side-by-side editorial comparison of Matrix and Rocket.Chat — release velocity, themes, recent moves, and the top alternatives to consider.
Matrix's changelog is a weekly community newsletter; no protocol or server releases visible in this window.
The entries for Matrix in this window are all 'This Week in Matrix' newsletter posts—weekly community roundups covering Matrix Live episodes, conference announcements, and ecosystem news. This reflects that Matrix's changelog feed is indexed against the newsletter rather than protocol specification releases or Synapse/Dendrite server releases. No MSCs (Matrix Spec Changes) or server version releases appear in this batch.
Rocket.Chat finishes the 8.8 calling work while the licence wall for SSO gets a date.
The 8.8 candidate line is winding down. rc.2 is a bare Meteor version bump with no user-visible change, following rc.1 which promoted Voice Call Screen Sharing to stable and turned on the in-room call interface for every call, screen sharing available or not, alongside repairs to a message list that could quietly load a whole room's history in the background. The release that still defines the line is rc.0: LDAP and SAML deprecated on non-Premium workspaces with 9.0.0 named as the cutoff, forced end-to-end encryption for new private rooms, classification banners for ABAC-managed rooms, and the apps-engine default runtime moved from Deno to Node.

The themes visible in Matrix Live across this window—local-first Matrix, privacy-preserving decentralized reputation (S13E06), and Continuwuity (an alternative homeserver implementation)—point to active experimentation at the protocol layer. The Matrix Conference 2026 countdown in the September newsletter suggests the organization is in a community-building phase ahead of a likely specification announcement.
The Matrix Conference 2026 is the next material event in the ecosystem. Local-first Matrix work visible in the newsletter suggests a potential Matrix Spec proposal around client-side data persistence and offline operation.

Two threads run at once and point in different directions. The calling stack keeps maturing on its own — voice, then screen sharing, now a consistent in-room surface for both — which is Rocket.Chat absorbing functions its users would otherwise reach for a separate tool to get. Against that, the 9.0 licence requirement for LDAP and SAML sorts the install base: regulated and government deployments that will pay, and unlicensed self-hosted workspaces that were there for the absence of a per-seat bill. The rc train itself has settled into a familiar shape, one substantive rc.0 followed by bumps and fixes.
Expect 8.8 to go final once the message-list fixes settle, with the LDAP and SAML licence requirement, not any calling feature, as the story of 9.0. The open question is whether the Deno-to-Node runtime switch surfaces app compatibility reports before then.
