A French telecom-fleet management tool quietly shipping fixes — no recent activity in over a year.
This Twist is not Doist's messaging app — it's a French B2B platform for managing corporate mobile telecom fleets (lines, SIM cards, terminal inventory, operator orders). The visible window is dominated by small audit-module fixes, SIM validation tweaks, mail parser improvements and one earlier Bouygues operator API connector. The most recent shipping activity dates to September 2024.
Slack is turning its app platform into an AI-agent surface — MCP on both ends, richer Block Kit.
The developer-facing changelog is busy and coherent: a Slackbot MCP client and expanded Slack MCP server tools, new Block Kit blocks (data visualization, data table, alert/card/carousel), streaming API updates for AI assistants, and a steady drumbeat of CLI and SDK releases.

The visible window is dominated by small audit-module fixes, SIM validation tweaks, mail parser improvements and one earlier Bouygues operator API connector. The most recent shipping activity dates to September 2024.
The trajectory in the captured window points to operational maintenance rather than category expansion: tightening data validation, fixing edge cases in audit reporting, supporting more telecom-data formats. The earlier Bouygues API connector hinted at a machine-to-machine ambition with the major French carriers, but follow-through (Orange, SFR) is not visible in this window. Public release cadence appears to have gone quiet.
Hard to call from the visible entries. If the Orange and SFR API connectors promised in 2024 ever shipped, they would have been the natural next chapter; their absence suggests either delayed delivery or a move to private release notes. Watch for whether public changelog cadence resumes at all.
The developer-facing changelog is busy and coherent: a Slackbot MCP client and expanded Slack MCP server tools, new Block Kit blocks (data visualization, data table, alert/card/carousel), streaming API updates for AI assistants, and a steady drumbeat of CLI and SDK releases.
Slack is positioning itself as both an MCP host (Slackbot calling external tools) and an MCP server (external agents acting in Slack), while Block Kit gains data-rich primitives and the streaming API matures for assistant experiences. The direction is making Slack a first-class surface for AI agents and data apps.
Expect deeper MCP capabilities and more data/visualization blocks, with continued frequent CLI/SDK releases supporting the agent-and-app platform push.
