Delta Chat
The email-as-messenger keeps shedding classic-email cruft for the Chatmail model
A side-by-side editorial comparison of Rocket.Chat and Notion — release velocity, themes, recent moves, and the top alternatives to consider.
Rocket.Chat grinds through the 8.7 release-candidate line, with a server-side OAuth and phishing-resistant MFA push landing in the mix.
Rocket.Chat's GitHub feed is a stream of release candidates — 8.7.0-rc.x on top of a just-closed 8.6.0-rc line. Most are patch bumps and dependency rolls, but the 8.7.0-rc.0 minor carries real security work: a fully server-side OAuth flow and phishing-resistant MFA, plus session-management refinements. The open-source, self-hosted team-chat cadence is steady and RC-heavy.
Notion is turning its workspace into an orchestration layer for external AI agents.
Notion has moved well past docs-and-wikis: the 3.5 Developer Platform and 3.6 release reposition it as an orchestration layer where external agents like Claude and Cursor, hosted Workers, and MCP connections do work alongside teams. Recent shipping is almost entirely agent infrastructure — shareable Workers, an agent-focused iOS app, calendar and Outlook control, and admin guardrails for spend and audit.

The open-source, self-hosted team-chat cadence is steady and RC-heavy.
The 8.6-to-8.7 arc leans on hardening: SSRF fixes, federation message-sync repairs, and now moving OAuth authentication entirely to the server to reduce token-exposure risk. Direction is security and reliability maturation of an already broad platform rather than net-new surface.
Expect 8.7.0 to reach a stable release once the rc line settles, carrying the server-side OAuth and MFA improvements as the headline security items.

The direction is consistent: own the surface where humans and agents collaborate, then meter it. Workers move to credit-based billing on August 11, the MCP connector list keeps expanding, and each new capability — more file types, calendar, external-agent orchestration — widens what an agent can do inside Notion rather than adding features for people directly.
Expect the Workers-to-credits cutover to anchor a usage-based pricing push, with more first-party MCP connectors and deeper external-agent orchestration as the next beats.
