About 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.
