What probably matters to youSection of the release
What
Tool invocation and turn stepping now go through the same event dispatch that plugins observe, rather than being called in line. This is the plumbing that lets a plugin see and act within a running turn.
Details
Each tool call builds an event input, dispatches through core and managed handlers, and does open/close bookkeeping around the call.
The interactive session subscribes to turn events and dispatches turn steps, appending their results as messages.
