Claude Code v2.1.77 · 16 Mar 2026
Lodash Internals Replaced
Entry Kind: in v2.1.77, 16 Mar 26
Changes Section of the release
Many lodash utility functions (ListCache, Stack, MapCache, Hash, deep clone helpers, typed array checks, key enumeration, etc.) have been removed and replaced with lighter native JavaScript implementations. This reduces bundle size without changing external behavior.
Evidence
Structural diff shows ~150+ removed lodash functions (ListCache, MapCache, Hash, Stack prototypes, baseClone, baseAssign, baseKeys, etc.)
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
