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 v2.1.181

HTML Sanitizer Library (xss/filterXSS) Removed

The xss / filterXSS library (~550 lines of bundled CSS-property whitelist and HTML parser code) has been removed from the CLI bundle. Any HTML sanitization that still occurs uses simpler inline escaping (CRr() at line ~161643 for &, <, >, ", ').

Evidence

Removed BZ6, UZ6, ucK, UcK, s58, t58, QZ6, flK, cZ6 modules (search for "filterXSS" — absent from new version)

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