About 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.
