Internal ChangesSection of the release
What
Several small internal fields were added, covering workflows, message batches, proactivity state and query tracking. None of them changes anything you can see yet.
A new error message also appears for when a subagent (a helper agent Claude starts to handle part of a task) did not start even though the hooks (your own scripts that run at set points) let it through: "the subagent did not start after the hooks passed it on".
Why
These look like preparation for features that are not visible yet. The start-failure message is the one piece you might actually meet.
