Canary Mail vs Openfire: 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 Openfire?
Openfire keeps its XMPP server current without changing what it is.
Openfire ships a maintenance release every one to two months, each a mix of dependency upgrades, MUC and pubsub correctness fixes, and occasional security hardening. 5.1.2 follows that shape exactly: Jetty, log4j2, and the PostgreSQL driver moved forward, three inapplicable Tomcat CVEs suppressed, and a set of MUC self-ping errors corrected to return the right XMPP error types. The last release with real feature content was 5.1.0 in June, which added channel binding and an admin console for failed server-to-server connections.

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.
Openfire
2.5COMMS
Openfire keeps its XMPP server current without changing what it is.
◆ Current state
Openfire ships a maintenance release every one to two months, each a mix of dependency upgrades, MUC and pubsub correctness fixes, and occasional security hardening. 5.1.2 follows that shape exactly: Jetty, log4j2, and the PostgreSQL driver moved forward, three inapplicable Tomcat CVEs suppressed, and a set of MUC self-ping errors corrected to return the right XMPP error types. The last release with real feature content was 5.1.0 in June, which added channel binding and an admin console for failed server-to-server connections.
◆ Where it's heading
The project's direction is protocol conformance and operational currency rather than new capability. Recent cycles have gone into XEP compliance details - self-ping error semantics, XEP-0398 presence handling, base64 whitespace tolerance - and into keeping the dependency tree clean enough to pass a scanner. That is a reasonable posture for infrastructure a decade into deployment, and nothing in the last six releases suggests a change of scope.
◆ Prediction
Expect the same cadence: another patch in four to eight weeks carrying library bumps and MUC or pubsub conformance fixes, with anything larger held for a 5.2 line.
