What
Claude Code has a check that tells whether it is running inside a bubblewrap sandbox or a Docker container. A sandbox is an isolated environment that limits what a program can reach, and bubblewrap is a Linux tool for making one. Docker runs programs in containers, which are a similar kind of isolated environment. The check answers "bubblewrap", "docker" or nothing, and it has been modified in this release.
Why
In practice this check reports the kind of environment Claude Code is running in. There is no visible change in how Claude Code behaves.
