What
Claude Code reads your git remote's fetch settings, which say which branches git downloads from that remote. Before, any failure of that read was treated as "not set". Now only the case where git says the setting does not exist counts as not set. Other failures are reported as unknown.
Why
A git error no longer leads Claude Code to act as if the settings were simply missing.
