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.

#

Version 2.1.24 was likely an internal/unpublished release, as this diff compares 2.1.23 directly to 2.1.25.

Build metadata changes only:

  • Version: 2.1.23 → 2.1.25
  • Build time: 2026-01-29T00:18:20Z → 2026-01-29T20:32:59Z (same day, ~20 hours later)

All other differences in the 6.9MB diff file are minification artifacts (variable/function name randomization) with no functional impact.
