What probably matters to youSection of the release
What
When a cloud session uses tools served from your computer, Claude Code shows notices about them. These notices now refer to a "Linux VM" (a virtual machine running Linux) instead of a "sandbox", for example "the Linux VM they must run in is still starting". They also now describe calls that are waiting on, or were refused by, your computer, rather than whether the tools are offered.
Why
The wording you see in these notices is different.
