What probably matters to youSection of the release
What
Before binding the socket used for messaging between sessions, Claude Code now creates the parent directory and sets it to owner-only (0700), then removes any stale socket. If you passed --messaging-socket-path yourself and it fails, the error tells you what to do.
Details
The message is "Choose a different --messaging-socket-path whose directory you own and can make private (0700)."
A path not given explicitly is resolved to an absolute path first.
Evidence
Choose a different --messaging-socket-path whose directory you own and can make private (0700).
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
