Twilio
Twilio is selling trust: branded calls, scoped keys, and stricter sender vetting.
A side-by-side editorial comparison of WATI and Slack — release velocity, themes, recent moves, and the top alternatives to consider.
Wati floods search with Astra-AI landing pages, but ships no visible changelog.
The crawled feed is Wati's SEO and marketing content — 'best WhatsApp API platform' pages, comparisons against Meta Business Agent, and landing copy for Astra, its AI-agent product (cross-session memory, native WhatsApp voice). It reads as marketing copy, not release notes.
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 messaging centers Astra as an AI-agent layer over the WhatsApp Business API — memory, voice, no-code agent building. The intent is clear, but this feed shows positioning rather than shipped changes.
Expect continued Astra-centric AI-agent messaging; without a real changelog source, product-move forecasts aren't supportable from 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.
