Canary Mail vs Proton Bridge: at a glance
What is Canary Mail?
Canary Mail ships maintenance across four platform lines; features have gone quiet since April.
Canary Mail publishes release notes per platform — Android, iOS, macOS and Windows each on their own version line — and every entry in the current top six is fixes only. The August wave put out iOS 5.22.0 and Mac 5.22.0 within a minute of each other carrying an identical changelog (Advanced View overwriting a custom SMTP username, plus crash fixes), with Android 3.99 alongside them fixing swipe-to-select misfires and PGP key handling. The most recent entries carrying a genuinely new capability are the April 5.19 releases, which let users dismiss unwanted compose suggestions.
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.
Canary Mail vs Proton Bridge: editorial side-by-side
Canary Mail
5.0COMMS
Canary Mail ships maintenance across four platform lines; features have gone quiet since April.
◆ Current state
Canary Mail publishes release notes per platform — Android, iOS, macOS and Windows each on their own version line — and every entry in the current top six is fixes only. The August wave put out iOS 5.22.0 and Mac 5.22.0 within a minute of each other carrying an identical changelog (Advanced View overwriting a custom SMTP username, plus crash fixes), with Android 3.99 alongside them fixing swipe-to-select misfires and PGP key handling. The most recent entries carrying a genuinely new capability are the April 5.19 releases, which let users dismiss unwanted compose suggestions.
◆ Where it's heading
This is a mature client in upkeep rather than expansion: across four months of entries, the only line labelled New is a suggestion-dismissal control. Two defect threads recur across platforms — PGP correctness (a key-unavailable fallback on Android, a decryption failure on Windows) and Gmail account-setup crashes — which points at encryption and onboarding as where the real bugs live. iOS and macOS now ship in lockstep with word-for-word identical notes, so those two lines are converging in practice even though the version numbers stay separate.
◆ Prediction
After four consecutive maintenance waves the next release is most likely another cross-platform stability pass; these entries do not show enough to say when the PGP or compose surface gets new capability rather than repairs.
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.
