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 v2.1.239

Windows pipe names no longer mangled by locale-specific lowercasing

You'll notice
Useful2 Signal1
Windows

On Windows, non-ASCII characters in your project path no longer corrupt the internal pipe name.

What

On Windows, the internal pipe name built from your project path now lowercases only A-Z runs instead of applying a full lowercase to the whole string, so non-ASCII characters in a path are left alone and locale rules cannot corrupt the name.

Details
  • Windows only.

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