What

Exiting plan mode via the ultraplan option now passes a note channel to the launched work, which posts a status message about what happened to the plan plus a follow-up instruction: "The ultraplan note above reports what happened to the plan. Do not respond to it - wait for the user's next message."

Details
  • The ultraplan option appears only when remote sessions are permitted by the allow_remote_sessions setting, an internal availability check passes, and a live remote session handle exists.
Evidence

The ultraplan note above reports what happened to the plan. Do not respond to it — wait for the user’s next message.

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
