Unclear It is not clear whether this means a 529 error is now retried automatically or handled some other way.
What
When Anthropic's API is too busy it answers with error 529, meaning overloaded. Claude Code now handles this error in the same way as error 429, which means too many requests.
Why
An overloaded response can now be handled like a rate limit rather than as a plain failure.
