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.
The URL pattern matching system used for web fetch permissions has been rewritten with more robust handling. It now uses a placeholder-based approach for wildcards, properly handles protocols, ports, and paths, and falls back to regex matching when the pattern isn't a valid URL.
Evidence
New WY$ function with comprehensive URL matching (search for "zzwildcard")
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
