That catalog moves from version 837 to version 994, issued at 2026-09-22T19:22:16Z. The build reports itself as version 2.1.281, built at 2026-09-23T02:22:43Z. The other changes in the build are renamed internal names with no change in behaviour.\n\n**Why**\n\nThe list of models Claude Code knows about out of the box now matches the newer catalog."}
