Claude Code v2.1.242 ·

Much of this release's diff is re-bundling, not behaviour

Most of this release's changed code is the build system moving modules, not features changing.

What

A large part of the changed code is the build system moving modules around; the affected features are present in both builds unchanged.

Details
  • Confirmed still present and unaltered: the /simplify and code-review prompts, prototype and whiteboard skills, todo and ExitPlanMode tool descriptions, design-sync capture, resync and preview-rebuild scripts, the remote-diff script's local mode, the keybindings and run-unit skills, directory sync, git bundle upload, device bash, the Workflow tool description, the ultraplan planning reminder, brief-mode reminder and Artifact tool schemas.
  • The Codex import path and the status line are recompilations; the status line now reads messages from a transcript snapshot instead of a live reference, with no visible difference.
Evidence

__ULTRAPLAN_TELEPORT_LOCAL__, tengu_ccr_bundle_upload

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
