Bug FixesSection of the release
What
When the API refuses to return output because of its content filtering policy, the error says "Output blocked by content filtering policy". Claude Code used to label any error containing that text as a content filter block. It now does so only when the error's status code, the number the API returns to describe a failure, is 400 or missing.
Why
Other errors that happen to mention that text are no longer reported as content filter blocks, so the reason Claude Code gives for a failure is more accurate.
