GitHub killed its model-hosting product and shipped stacked PRs in the same week.
A side-by-side editorial comparison of Flarum and Slack — release velocity, themes, recent moves, and the top alternatives to consider.
Flarum's 2.0 has been in release-candidate territory for most of a year.
Flarum is an open-source forum framework whose entire recent release history is the 2.0 train — beta.8 in March, then five release candidates from April through July. The candidates ship on a three-to-six week rhythm, and most of them publish nothing beyond a pointer to the changelog file in the tag. The last releases carrying visible detail were the earlier ones, where the work was database and rendering performance plus extension-compatibility fixes.
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.

The substance that is visible points at making large forums viable: eliminating N+1 queries on the discussion list, adding a composite index to fix slow unread-notification counts, and caching scheduler timestamps. Those are the changes a forum makes when instances have outgrown the original query patterns. The steady RC cadence with no beta regression suggests a stabilisation grind rather than continued feature work — but the opaque release notes make the remaining scope hard to read from outside.
A 2.0 stable release is the obvious next step, though five candidates without a published scope makes the timing unclear. Watch whether rc.6 arrives on the same three-to-six week spacing or the gap widens.

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.
