What probably matters to youSection of the release
What
Launching an app during computer use now has two modes: a background launch that does not bring the app to the front and leaves it reachable through the per-app tools, and the normal launch that brings it forward. The launch returns a window id when one is available.
Details
The request to record a teach-mode demonstration now has an explicit declined result, which tells the model not to ask again in this session.
A separate refusal, cu_lock_held, is returned when another Claude session took the computer while the approval prompt was still open.
Screenshot coordinate conversion now reports which coordinate frame a point is in whenever that frame differs from the scaled image.
Background launching needs a host that supplies app-scoped control and an app lock already held; otherwise the front-of-screen behaviour applies.
Evidence
In background app mode, the launch does NOT bring it to the front
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
