Claude Code v2.1.223 ·

More on-disk state moved behind the abstract state store

Some local lock and cache files can now live in a shared state store instead of loose files.

What

Five pieces of local state became addressable as named state entries rather than only files under the Claude home dir.

Details
  • covers the auto-updater lock, GitHub PR status cache, daemon lock, deep-link-register-failed marker and last-cleanup stamp
  • the updater's acquire and release functions take an optional store and delegate to store-based variants when one is given
  • without a store they keep using the .update.lock file and gh-pr-status-cache.json
  • the store-backed path only runs when a call site passes a handle, so this is per call site
Evidence

AutoUpdater: failed to release update lock:

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