DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. 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.

Claude Code v2.1.232

Per-session state consolidated into roughly two dozen typed stores

Under the hood
Useful1 Signal1
Session State

Counters and latches now belong to a session rather than the whole process.

What

Mutable state that lived in process-wide variables now hangs off a single per-session object, so counters and latches belong to a session rather than the process.

Details
  • New domains alongside the existing ones include cost ledger, model selection, request journal, prompt assembly, session flags and scratch, surface capabilities, turn budget, user presence, hook registry, MCP session wiring, invoked skills, identity and conversation latches.
  • Accessors for total token and line counters, refusal-fallback model latches, prompt id and index, and approved MCP servers now read from these stores.
  • Sessions forked for a different project keep sharing the root's stores, so behaviour should be unchanged.
Evidence

promptAssembly

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