What
A worktree is an extra working copy of a git project that shares the main project's .git folder. When the main project's git files change while Claude Code is reading them, it now says: "This worktree's git files, in its main project's .git directory, changed while they were being read. Try again; if it keeps happening, check what else is changing that .git directory." Before, this case showed the generic message that the .git directory could not be read.
The messages for when git is not found also have extra text added at the end.
Why
A brief clash with something else changing the git files now gets its own diagnosis and a next step, instead of a vague error.
