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.

Session Rename

What

Sessions can now be renamed programmatically via the SDK, and remote sessions automatically get renamed based on their git branch.

Details
  • New rename_session control action with description: "Sets the user-facing title for the current session."
  • Title validation requires non-empty strings
  • Remote sessions now include onRenameSession callbacks and parseGitRemote for automatic naming based on the repo branch
Evidence

Session rename handler (search for "rename_session" and "title must be non-empty")

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