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.

What is mailcow?

mailcow's release notes are almost entirely upstream security currency.

mailcow ships named seasonal releases with lettered revisions, and nearly every revision exists to pull in an upstream security fix - Redis, ClamAV, SOGo, Rspamd, nginx, unbound, Postfix. Revision B of the Mooly 2026 release updates Redis 7.4.10, ClamAV 1.4.6, and SOGo 5.12.10, adds minor web UI and nginx hardening, and removes a legacy DeltaChat sieve rule. The last release with genuinely new features was the March cut, which added forced 2FA, ACME DNS-01 challenges, and a passwordless autodiscover endpoint.

Friendica vs mailcow: editorial side-by-side

F0.0

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.

5.0

mailcow's release notes are almost entirely upstream security currency.

◆ Current state

mailcow ships named seasonal releases with lettered revisions, and nearly every revision exists to pull in an upstream security fix - Redis, ClamAV, SOGo, Rspamd, nginx, unbound, Postfix. Revision B of the Mooly 2026 release updates Redis 7.4.10, ClamAV 1.4.6, and SOGo 5.12.10, adds minor web UI and nginx hardening, and removes a legacy DeltaChat sieve rule. The last release with genuinely new features was the March cut, which added forced 2FA, ACME DNS-01 challenges, and a passwordless autodiscover endpoint.

◆ Where it's heading

For a self-hosted mail stack that bundles a dozen upstream components, keeping current with their CVEs is the product, and mailcow has organized its release cadence around exactly that. The pattern is consistent: a named release with some feature content every few months, then lettered revisions that are pure security currency plus small web UI escaping and validation fixes. The web interface is where mailcow's own code gets hardened - HTML escaping in quarantine views and sieve editors recurs across several revisions.

◆ Prediction

Expect the next entry to be another lettered revision carrying upstream updates, with the next named release likely bundling whatever feature work has accumulated since March.
