DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Claude Code v2.1.242

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

Under the hood
Useful1 Signal1
Bundle

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.

Other releases about the same thing. Found by shared names or similar wording; neither means one caused the other.
