What
Claude Code can run sessions in the background in a separate process. When that process is from an older version, Claude Code normally restarts it on the new version. Now Claude Code first compares the sign-in environment variables (settings passed to a program when it starts) the background process was started with against the current ones. On Linux and WSL it reads these from the running process.
If they differ:
the outdated background session is not restarted
a background session Claude Code has taken over is not upgraded automatically
Claude Code records that the restart was held back
This is controlled by a remotely managed switch.
Why
An upgrade restart could otherwise move a background session onto a different account or profile without you noticing.
