Proton Bridge vs Rocket.Chat: at a glance
What is Proton Bridge?
Proton Bridge has re-accelerated, with a quality-and-security pass across error UX, FIDO2, and Go modernization.
After a long pause through mid-2025, Proton Bridge resumed steady releases in early 2026 and has now shipped four versions in five months (v3.22 through v3.25). The work is uniformly internal: friendlier error messages, a Go 1.26 toolchain bump, FIDO2 path fixes, IMAP robustness, certificate-chain validation tightening, and the March 2026 security-patch sweep. Visible user-facing additions are limited to MacOS26 icon support and quality-of-life polish.
What is Rocket.Chat?
Six release candidates into 8.7, and five of them are version bumps.
Rocket.Chat is six candidates deep into 8.7.0, and the visible content of that train is thin. Five of the six most recent entries carry an identical body: a Meteor package bump with internal typings following. The engine floor holds steady across the whole window at Node 22.22.3, Deno 2.3.1, MongoDB 8.0, and Apps-Engine 1.65.1-rc.0. The one substantive change in the cycle sits back in 8.7.0-rc.0, which added session identification to the device management API.

Proton Bridge
2.5COMMS
Proton Bridge has re-accelerated, with a quality-and-security pass across error UX, FIDO2, and Go modernization.
◆ Current state
After a long pause through mid-2025, Proton Bridge resumed steady releases in early 2026 and has now shipped four versions in five months (v3.22 through v3.25). The work is uniformly internal: friendlier error messages, a Go 1.26 toolchain bump, FIDO2 path fixes, IMAP robustness, certificate-chain validation tightening, and the March 2026 security-patch sweep. Visible user-facing additions are limited to MacOS26 icon support and quality-of-life polish.
◆ Where it's heading
The product is in active maintenance mode rather than feature expansion. Investment is going into making the local sync layer more robust — mailbox conflict resolution, IMAP IDLE kill switch, vault retries on Linux — and the auth surface harder, with FIDO2 polish and TLS pin scoping. The arc reads as catching up on technical debt and shoring up security posture after a quieter year, not reshaping the product.
◆ Prediction
Expect the v3.2x cadence to continue with similar bug-fix and security flavor: more Go toolchain work, incremental IMAP edge-case handling, and continued error-UX tightening. The release notes do not surface anything that would hint at a v4 reshape or a meaningful new capability in the near term.
Rocket.Chat
6.3COMMS
Six release candidates into 8.7, and five of them are version bumps.
◆ Current state
Rocket.Chat is six candidates deep into 8.7.0, and the visible content of that train is thin. Five of the six most recent entries carry an identical body: a Meteor package bump with internal typings following. The engine floor holds steady across the whole window at Node 22.22.3, Deno 2.3.1, MongoDB 8.0, and Apps-Engine 1.65.1-rc.0. The one substantive change in the cycle sits back in 8.7.0-rc.0, which added session identification to the device management API.
◆ Where it's heading
This is a stabilization run rather than a feature cycle, and the same shape repeated in 8.6.0, whose rc.1 through rc.3 read the same way. Each cycle front-loads its minor changes into rc.0, then spends weeks on version bumps with isolated fixes folded in. For anyone reading the changelog, that means almost nothing is learnable between an rc.0 and the eventual release.
◆ Prediction
Expect 8.7.0 to reach general availability with a note consolidating the rc.0 session-management change and the scattered candidate fixes; on this pattern the next real signal comes with 8.8.0-rc.0, not from the remaining 8.7 candidates.
