What probably matters to youSection of the release

OAuth refresh delegation installs only when CLAUDE_CODE_SDK_HAS_OAUTH_REFRESH is set and the entrypoint matches.

What

Instead of refreshing the login token itself, the client can hand that job to the program embedding it. This is installed only when CLAUDE_CODE_SDK_HAS_OAUTH_REFRESH is set and CLAUDE_CODE_ENTRYPOINT names one of a fixed set of entry points, so it is off by default.

Details
  • Whether the bridge was installed is reported as oauth_bridge in the session-started event.
