Claude Code v2.1.242 ·

The bundle is split into chunks loaded on demand

The program is split into pieces loaded as needed, changing startup shape but nothing you interact with.

What

Code that previously all lived in one file is now split across separate chunk files pulled in as they are needed, which changes startup and memory shape but nothing you interact with.

Details
  • Over a thousand call sites now load a chunk by path; the previous build had none and resolved everything inline.
  • The large design-sync skill prompts have moved out of the main file into a chunk and are still shipped in full.
  • Deep-link handling, config enabling, and the two directory-sync engines are now opened this way, which means those paths can fail at load time. The sync engines record _engine_open_failed and _engine_open_timeout for that case.
Evidence

import("/$bunfs/root/chunk-XXXXXXXX.js")

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