mailcow vs Friendica: at a glance
What is mailcow?
Six releases, and every one of them is a security update in some form.
mailcow ships on a monthly tag with lettered revisions, and this window contains no release that isn't security-driven. The May line ran to three revisions in two weeks — an unnamed fix with a CVE identifier withheld until later, SOGo 5.12.8 covering four upstream issues, an unbound CVE, HTML escaping added to the quarantine table, sieve filter editor and queue manager. July brought Rspamd 4.1.0 and later 4.1.4, nginx 1.30.3 and a CVE fix, Postfix moved off bookworm, and a release described only as hardening.
What is Friendica?
Friendica keeps betting on being the fediverse node that speaks everyone else's protocols.
Friendica is a self-hosted decentralised social platform, released on calendar versions two or three times a year with codenames and a consistent structure: a handful of highlights, a security-fix credit, and a pointer to the changelog. The recent run — 2023.12, 2024.03, 2024.08, 2024.12, 2026.01, 2026.05 — shows the cadence thinning, with a full year between 2024.12 and 2026.01. Nearly every release credits externally reported security issues, most recently from Doyensec working with Mastodon.

mailcow
5.0COMMS
Six releases, and every one of them is a security update in some form.
◆ Current state
mailcow ships on a monthly tag with lettered revisions, and this window contains no release that isn't security-driven. The May line ran to three revisions in two weeks — an unnamed fix with a CVE identifier withheld until later, SOGo 5.12.8 covering four upstream issues, an unbound CVE, HTML escaping added to the quarantine table, sieve filter editor and queue manager. July brought Rspamd 4.1.0 and later 4.1.4, nginx 1.30.3 and a CVE fix, Postfix moved off bookworm, and a release described only as hardening.
◆ Where it's heading
Two distinct pressures are visible. One is upstream: mailcow bundles Postfix, Rspamd, SOGo, nginx, unbound and Dovecot, so every one of their advisories becomes a mailcow release, and the base image migration from bookworm to trixie is that same maintenance surfacing at the OS layer. The other is the project's own web UI, where output escaping is being retrofitted view by view — quarantine table, sieve editor, queue manager, quarantine overview — which reads as a systematic pass rather than isolated reports. Earlier releases in the feed show where feature work went when it happened: forced 2FA, ACME DNS-01 challenges, and admin controls over EAS and DAV access.
◆ Prediction
Expect the monthly-plus-revisions rhythm to continue with upstream component bumps driving most of it, and the web UI escaping pass to reach the remaining admin views.
Friendica
0.0COMMS
Friendica keeps betting on being the fediverse node that speaks everyone else's protocols.
◆ Current state
Friendica is a self-hosted decentralised social platform, released on calendar versions two or three times a year with codenames and a consistent structure: a handful of highlights, a security-fix credit, and a pointer to the changelog. The recent run — 2023.12, 2024.03, 2024.08, 2024.12, 2026.01, 2026.05 — shows the cadence thinning, with a full year between 2024.12 and 2026.01. Nearly every release credits externally reported security issues, most recently from Doyensec working with Mastodon.
◆ Where it's heading
Two lines of work dominate. The first is connectors: an initial Bluesky bridge in 2023.05 made bi-directional by 2023.12, Tumblr support maintained throughout, and ATproto account integration plus Bridgy Fed support improved in 2026.05. The second is Channels — the user-defined algorithm for sorting the network stream — introduced in 2023.12 and given performance and sorting work in every release since. Running against both is a deliberate pruning of legacy: OStatus dropped in 2024.12 after the project measured how few servers still needed it, and the fancybox addon deprecated alongside it.
◆ Prediction
Expect the next release to continue the ATproto and Bridgy Fed integration work and further Channels performance tuning, with the accessibility review started in 2026.01 producing more fixes. Given the year-long gap before 2026.01, the cadence itself is the uncertain part.
