A one-binary mail server learning to behave like production infrastructure.
A side-by-side editorial comparison of Trumpia and Slack — release velocity, themes, recent moves, and the top alternatives to consider.
Trumpia ships SMS explainers weekly and product notes never.
Every entry in this window is educational or promotional: emoji meanings, a KPI list, a drip-campaign definition, opt-in psychology, an RCS-to-SMS how-to, and a Forbes mention. There is no release note, version number, or feature announcement anywhere in the feed.
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.

This is a top-of-funnel SEO program rather than a changelog, so it carries almost no signal about where the product is going. The mild topical drift is toward RCS and toward consent and compliance, which is where SMS vendors currently face the most pressure, but nothing here shows what Trumpia is building in response.
Expect the same cadence of definitional SMS posts to continue. Nothing in these entries supports a prediction about the product itself — that would need a source other than this feed.

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.
