A side-by-side editorial comparison of Proton Bridge and Rocket.Chat — release velocity, themes, recent moves, and the top alternatives to consider.
Proton Bridge is in pure maintenance: security patches and RFC compliance fixes dominate 2026
Proton Bridge has shipped six releases since February, none of which introduce user-visible features. The work is security vulnerability patching (August 2026 CVEs), RFC3501 IMAP compliance fixes, Go toolchain upgrades, and bug fixes in the Gluon IMAP server component. The v3.24.0 cycle added IMAP connection limiting and buffer pooling for message decryption — the most substantive user-affecting work in the reviewed period.
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.

Proton Bridge is in a sustain phase. The Gluon subsystem is getting more robust error reporting, CPU/memory bounds on the RFCP parser, and feature flags for controlled rollouts — signals of hardening a component that has historically caused reliability issues. No new end-user capabilities are visible in the roadmap from the changelog alone.
The next release will likely be another security or compatibility patch. Meaningful feature expansion would require Proton to signal a direction change for Bridge publicly, and nothing in this changelog points toward one.

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.
