What probably matters to youSection of the release
What

The check that tests which models are available on Google Vertex AI used to either skip signing in, when CLAUDE_CODE_SKIP_VERTEX_AUTH is set, or use the default sign-in. It now also has a bearer mode, where a bearer token (a single access key sent with each request) is used to sign in.

In this build the value that would supply that token is always empty, so the new mode is never used.

Why

Nothing changes for Vertex AI users yet. It is groundwork for signing in to Vertex AI with a bearer token.
