    The release notes list the qwen4 context-window fallback when no upstream catalog entry defines the model.

  2. Unconfirmed

    The merged PR adds a 1,000,000-token fallback for qwen4 identifiers, including max, plus, coder-plus, dated names and qwen4.5; a model catalog entry takes precedence. The PR does not verify a real Qwen4 endpoint.
