DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Session registry can now be watched for state changes

Sessions

Long-lived session state can now be watched, likely plumbing for a status indicator.

A session-state subscription emits armed and off states but nothing user-visible consumes it.

What

The registry that tracks long-lived sessions gained a way to subscribe to a session's state, polling and emitting normalized values such as an armed state naming the engine and direction, or an off state naming the reason. It also counts when a session's full listing grows past its allowed size. Nothing user-visible consumes it yet; it looks like plumbing for a status indicator.

Details
  • The polling interval is set by an internal constant whose value is not visible in the build.
