What probably matters to youSection of the release
What
When you send a message to another Claude session and the recipient holds, denies, or lets it expire, your session now prints a warning line and quietly tells the model not to sit waiting for a reply. Receipts arrive in batches of up to 200 per status and are de-duplicated per recipient address.
Details
Two surfaces per receipt: a visible warning line, and a low-priority note injected into the conversation so the model stops blocking on an answer.
Covers held, denied and expired outcomes.
