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 Signal Desktop?

Signal Desktop's 8.36 beta adds favorite sticker packs after a fix-only week.

Signal Desktop ships a beta roughly weekly, and most builds since September carry only generic fix notes. v8.36.0-beta.1 adds favorite sticker packs, so the ones a user relies on stay at hand. It follows the fix-only v8.35.0-beta.1 and v8.34.0-beta.1, which added contact sharing from desktop and better audio device handling.

Proton Bridge vs Signal Desktop: 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.

S5.0

Signal Desktop's 8.36 beta adds favorite sticker packs after a fix-only week.

◆ Current state

Signal Desktop ships a beta roughly weekly, and most builds since September carry only generic fix notes. v8.36.0-beta.1 adds favorite sticker packs, so the ones a user relies on stay at hand. It follows the fix-only v8.35.0-beta.1 and v8.34.0-beta.1, which added contact sharing from desktop and better audio device handling.

◆ Where it's heading

The desktop app is closing gaps with mobile one feature at a time, separated by maintenance betas. Visible features arrive about every two to three builds.

◆ Prediction

The next feature beta is likely within one or two builds, based on the cadence since October. The entries don't indicate what it will contain.
