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 v2.1.112

  • The Haiku model selector descriptions ("Haiku 3.5" and "Haiku 4.5") appear swapped between two internal functions compared to the prior version, but both strings exist with identical counts in both versions (6 occurrences of "Haiku 3.5", 16 of "Haiku 4.5"). This is internal code reorganization with no user-visible effect.
  • Import style was refactored from default imports to named/destructured imports for several Node.js built-in modules (child_process, crypto, node:os, etc.). This is purely internal cleanup with no behavioral change.
