Claude Code Removes Ultraplan and Changes `/fork` to Create Its Own Worktree
2.1.222 removes the ultraplan feature outright. Separately, 2.1.221 changes sessions forked with `/fork` to create a new worktree of their own instead of working in the original session's checkout, and changes background sessions to commit and push to preserve work, open a draft PR only when the task calls for one, follow your CLAUDE.md git instructions, and always end by reporting where the work lives. Fork-into-its-own-worktree is a behavioral change worth knowing before your next branching session — forks no longer share your working tree.
