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 v2.1.79

  • The JWT library bundled within Claude Code has been replaced: the old multi-file jwa/jws/Buffer-based implementation was removed in favor of a leaner inline version with improved error handling for missing HMAC secrets.
  • The claude-developer-platform skill content has been significantly updated with new model references (Opus 4.6, Sonnet 4.6), adaptive thinking guidance, compaction documentation, and multi-language SDK support information including Go, Ruby, C#, and PHP.
