What's New in Fuzzball 4.2


Fuzzball 4.2 does more of the work, and lets you approve the parts that matter. Jonathon Anderson shows it running: an AI agent drives Fuzzball over MCP, workflows launch their own follow-on work through a new in-workflow API, and the cluster scores its own hardware and routes around a failing node.

Join us September 17 at 2:00 PM ET / 11:00 AM PT.

What we'll cover

  • An AI agent that drives Fuzzball over MCP, under permissions you hold.

  • Workflows that launch and manage more workflows through a scoped API.

  • Node health that keeps the scheduler off a failing node.

What you'll leave with

  • A clear read on what the 4.2 upgrade changes for a cluster you run.

  • The agent loop seen running against real work, not described on a slide.

  • A concrete next step, whether you're upgrading or evaluating.
