What is Proton Bridge?

Proton Bridge v3.27.2 adds support for the oo7 keyring on Linux.

Proton Bridge's releases in 2026 have been almost entirely maintenance: monthly vulnerability patches, Go toolchain bumps, IMAP RFC-compliance fixes and recovery from corrupted sync state files. v3.27.2 adds one item, support for the oo7 keyring service, a Rust-based Secret Service implementation used on newer Linux desktops.

What is Rocket.Chat?

Rocket.Chat 9.0 reaches rc.8 with a migration fix as candidates shrink to single patches.

The 9.0 candidate line opened on 27 October with a licensing change: LDAP, SAML and Custom OAuth now require a premium plan. Since rc.4 the candidates have been fixes, and rc.8 on 7 November carries a single one: servers that started during another server's database migration no longer keep stale settings until restart. On 6 November 8.9.1 LTS backported the 9.0 load fixes plus a security hotfix.

Proton Bridge vs Rocket.Chat: editorial side-by-side

P2.5

Proton Bridge v3.27.2 adds support for the oo7 keyring on Linux.

◆ Current state

Proton Bridge's releases in 2026 have been almost entirely maintenance: monthly vulnerability patches, Go toolchain bumps, IMAP RFC-compliance fixes and recovery from corrupted sync state files. v3.27.2 adds one item, support for the oo7 keyring service, a Rust-based Secret Service implementation used on newer Linux desktops.

◆ Where it's heading

Bridge remains a stable compatibility layer rather than a growing product. The small additions that do land are about running cleanly on more desktop environments.

◆ Prediction

Expect the next monthly security patch release; the entries show no sign of feature work.

Rocket.Chat logo6.3

Rocket.Chat 9.0 reaches rc.8 with a migration fix as candidates shrink to single patches.

◆ Current state

The 9.0 candidate line opened on 27 October with a licensing change: LDAP, SAML and Custom OAuth now require a premium plan. Since rc.4 the candidates have been fixes, and rc.8 on 7 November carries a single one: servers that started during another server's database migration no longer keep stale settings until restart. On 6 November 8.9.1 LTS backported the 9.0 load fixes plus a security hotfix.

◆ Where it's heading

9.0 is in stabilization: each candidate is smaller than the last, and the load fixes are being carried to the LTS line rather than held for the major. Native LiveKit video is being promoted step by step, from alpha to beta and now as the named default provider option.

◆ Prediction

With rc.7 down to a handful of fixes, 9.0.0 GA is the next likely release, followed by further 8.9.x LTS patches carrying the same fixes.
