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 v2.1.227

One-line text fields no longer accept Unicode line separators

You'll notice
Useful1 Signal2
Skills

Exotic Unicode line breaks can no longer sneak into single-line skill proposal fields.

What

The squeeze that flattens skill proposal text to a single line collapsed only carriage returns and newlines. It now also collapses U+2028 and U+2029, the Unicode line and paragraph separators, so those can no longer slip a line break into a one-line field.

Evidence

/[\r\n\u2028\u2029]+/g

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