Canary Mail vs Signal Desktop: 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 Signal Desktop?
Signal's beta train keeps trickling small comfort settings between maintenance drops
The beta line ships roughly weekly and most releases carry nothing user-facing. The newest adds two zoom levels — 110% and 90% — to appearance settings, following a member search field on the group settings page a week earlier. The heavier work sits further back: an End Group control for admins in 8.19, and disappearing call events plus sticker pack reordering in 8.20.

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.
Signal Desktop
5.0COMMS
Signal's beta train keeps trickling small comfort settings between maintenance drops
◆ Current state
The beta line ships roughly weekly and most releases carry nothing user-facing. The newest adds two zoom levels — 110% and 90% — to appearance settings, following a member search field on the group settings page a week earlier. The heavier work sits further back: an End Group control for admins in 8.19, and disappearing call events plus sticker pack reordering in 8.20.
◆ Where it's heading
Two threads alternate here. Group management accumulated real controls through 8.17-8.19 — deleting others' messages, ending a group outright — and has since narrowed to findability. The newest release moves off groups entirely into display comfort, which alongside three maintenance-only betas reads as feature work thinning rather than redirecting.
◆ Prediction
On the evidence here the next content-bearing beta is another small settings-surface addition rather than a return to group administration, since the last two features have both been comfort options rather than capability.
