Claude Code v2.1.221 ·

Large amount of module-initializer churn with no visible behaviour

Dozens of module-loading tweaks shuffled around internally with no effect you can see.

What

About forty changes in this build are single added or removed initializer calls at the top of lazily-evaluated module bodies.

Details
  • Mostly extra dependency modules pulled in, with a couple dropped.
  • A handful of one-line function bodies pair up differently between builds purely because of minified-name reassignment.
  • No user-visible behaviour could be attributed to any of them individually; they are consistent with dependency-graph reshuffling caused by the other changes here.
Evidence

iDp = require("crypto");

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