What probably matters to youSection of the release
What
Around two dozen prompt and dialog types are now marked as yielding to panels, including every permission prompt (bash, browser, file, skill, webfetch, powershell, and both plan-mode prompts) plus cost threshold warnings, goal proposals, computer-use approval, setup and the Chrome install upsell. While you have a panel open that you opened yourself, an agent-initiated dialog of one of these kinds is suppressed rather than interrupting you. No flag or environment variable guards this.
Details
A new arbitration mode "panel" joins the existing "legacy-dialog" and "typing" choices.
Suppression requires both a user-invoked panel open and the pending request marked as yielding.
The flag does not exist at all in v2.1.247.
