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 v2.1.137

0 entries read diff v2.1.136 → v2.1.137 Markdown

Version 2.1.137 appears to be a build-only CLI release. The filtered AST diff shows 100.0% structural similarity with no added or removed declarations, and the AST-extracted string diff contains only the new build timestamp and git SHA.

Evidence: Version metadata changed from 2.1.136 to 2.1.137; the only added string literals are "2026-05-08T23:01:55Z" and "88a017e5d1d4c7de4e6de6a496ac08c9c1b77d79".

Published verbatim by Anthropic for v2.1.137. Text is unmodified from the upstream changelog. Everything else on this page came out of the bundle instead, which is why the two lists don't match.
