What changed in Claude Code 2.1.221?

In our words, from the release notes — never copied.

  • The VS Code integration introduces an expandable summary mode that hides detailed tool operations to clean up the workspace, alongside several fixes for Vim keybindings and emoji autocomplete.
  • The developer tool now secures credential files within sandboxes on Linux and WSL, and addresses multiple flaws that allowed command execution checks to be bypassed in Bash and PowerShell environments.
  • A transition to native kernel calls on Windows prevents security software from flagging the utility during startup, while revamped conversation prefixing lowers the cost of automated model calls.
  • Forked developer sessions now isolate their file systems using distinct Git worktrees, while automated background tasks have been adjusted to systematically save code changes and document where they are stored.
  • Extensibility is improved by automatically updating catalogs before failing a plugin installation, allowing safe additions to run immediately, and alerting users to naming issues that would block marketplace synchronization.
