What
Claude Code uses a lock file so that two processes do not act on the same thing at once. When it checks a lock and finds no record of who owns it, it now looks at the lock file again:
- if the file's last-modified time is the one expected, it reports that there is no owner record, as before
- if the time is different, it reports that the lock changed
It used to report that there was no owner record in both cases.
Why
This makes the diagnosis a little more precise. A lock that was replaced in the meantime is no longer mistaken for one that simply has no owner.
Something disagreesSomething we can check disagrees with this entry, or the writer said they could not settle it.
