Krisp
Krisp turned noise cancellation into a contact-center AI stack — and now defends it against deepfakes.
A side-by-side editorial comparison of Openfire and Notion — release velocity, themes, recent moves, and the top alternatives to consider.
Openfire's 5.1 line pairs XMPP channel binding with a steady cleanup of its own crypto
Six releases across the 5.0 and 5.1 lines, each a long list of numbered improvements and bug fixes. The 5.1.0 release is the substantive one: support for channel binding, an admin console page for reviewing failed server-to-server connection attempts, visible S2S ports, and removal of a hardcoded initialization vector and a weak SHA-1-derived Blowfish key. The rest is multi-user chat correctness, pubsub behaviour and dependency currency.
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 rest is multi-user chat correctness, pubsub behaviour and dependency currency.
Two consistent threads run through the window: replacing the older cryptographic shortcuts still sitting in the codebase, and making federation failures diagnosable rather than silent. Multi-user chat and pubsub keep generating the highest volume of fixes, which is a fair map of where a working XMPP server actually spends its time.
Expect the 5.1 line to continue with MUC and pubsub fixes plus further dependency upgrades, with any remaining legacy crypto paths the most likely target for the next round of hardening.

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.
