DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Renaming a session warns when other sessions may keep the old name

Useful2 Signal1
Sessions

Renaming a session now warns you when the new name didn't reach other running sessions, pointing at --debug.

--debug
What

A rename that applied locally but failed to reach the shared record of running sessions now says so, and points you at --debug for the cause. It used to fail silently apart from an unrelated line about a PID file.

Details
  • The rename result appends the caveat only when the shared record was not updated.
  • Also fixes a case where the confirmation printed the internal result object instead of the new name.
Evidence

Other sessions may still show the old name: the session registry could not be updated (run with --debug for the cause), applied locally but the session registry record was not updated

Strings lifted out of the shipped bundle, so the claim above can be checked against them.

Related

Other releases about the same thing. Found by shared names or similar wording; neither means one caused the other.
