What probably matters to youSection of the release
The warning shown when Claude Code doesn't recognize a model and falls back to an assumed context window for auto-compact has been reworded. It now consistently references CLAUDE_CODE_DISABLE_UNKNOWN_MODEL_WINDOW_ENFORCEMENT=1 as the way to restore the previous wait-for-the-API behavior.
