What
When Claude Code reports that a message is missing, the hint shown with it has a different wording. It used to tell you to try again or sign in again. It now says the message may be an earlier one that was delivered a second time. It tells you to try again only if you sent it and Claude has not already acted on it.
Why
This makes you less likely to send the same request twice when Claude has already handled it.
