Mattermost ships v11.8 compliance controls amid heavy sovereign-defence content
A side-by-side editorial comparison of Morgen and Slack — release velocity, themes, recent moves, and the top alternatives to consider.
Morgen has cleared the v4 rebuild and is using the new foundation to add web and AI features.
Morgen 4 went out of beta in January after an extended ramp, replacing the internal architecture and dropping legacy CalDAV and Exchange on-premise support. Subsequent releases have layered new capability on the new base: centralized tag management, extended CalDAV support, AI Planner reliability, Microsoft Planner task quotas, and routine events that merge into existing blocks. The cadence is biweekly small releases, with one duplicate publish noted in February.
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 cadence is biweekly small releases, with one duplicate publish noted in February.
The product is converting the Morgen 4 platform investment into shipping velocity, especially around AI scheduling, task integrations, and cross-platform reach (the web edition is now possible). Expect more polish on AI Planner and broader integration coverage as the architecture pays back the rewrite cost. The v3 sunset is scheduled, so future work targets v4 only.
The next directional move likely brings the Morgen web experience to general availability, plus AI Planner enhancements that reason over routines and tasks across calendars. More CRM and task-system integrations should follow now that the data layer is unified.
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.
