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.

Faster Fuzzy Matching with Damerau-Levenshtein

The string distance algorithm used for fuzzy matching (e.g., command suggestions for typos) has been upgraded from standard Levenshtein distance to Damerau-Levenshtein distance, which also considers character transpositions. A configurable maxEditDistance parameter is now available.

Evidence

Damerau-Levenshtein algorithm in EKY() at line ~421613

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