A one-binary mail server learning to behave like production infrastructure.
A side-by-side editorial comparison of Slack and Friendica — release velocity, themes, recent moves, and the top alternatives to consider.
Slack is shipping its developer platform to coding agents, not only to developers.
The developer changelog runs two tracks at once. One is a routine modernization wave across the client libraries: Bolt for JS reached v5, the Node SDK packages took coordinated major versions, and the CLI shipped twice in ten days. The other is newer and smaller in volume but larger in intent, aimed at AI tooling rather than at people writing apps by hand.
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.

The MCP and Skills plugin is the clearest signal of where this is going: Slack is packaging its own platform knowledge for consumption by coding agents, and naming Claude Code and Cursor as the first targets rather than shipping a generic endpoint. Meanwhile the SDK work is clearing debt that would get in the way, dropping axios for native Fetch, removing the deprecated Workflow Steps from Apps feature, and raising the Node floor to 20. Modern runtime, fewer legacy surfaces, then agent access on top.
The plugin ships for two named agent clients today, so the obvious next step is broadening that list or folding the skills into the CLI itself. The entries do not indicate whether Slack intends the MCP server to reach runtime app behaviour or stay a build-time developer aid.

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.
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.
