What probably matters to youSection of the release
What
A PermissionRequest hook can now stop the turn, not just the one tool call. The hook result carries an interrupt field alongside the decision; a hook that denies and sets interrupt true interrupts the turn. Denials without a message use "Permission denied by PermissionRequest hook". Allow decisions always carry interrupt false.
Evidence
Permission denied by PermissionRequest hook
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
