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.

Session state and module caches reorganised into resettable objects

Under the hood
Useful2 Signal2
Session State

Session state is built by a factory so caches clear as a unit instead of individually.

What

Session state is now built by a factory with a nested project group, and many long-lived caches (git availability, plugin agents, ripgrep availability and file counts, footer-link regexes, team-artifact scanning, temp directory resolution, marketplace loads, messaging socket state) became classes with an explicit reset. Per-session state is cleared as a unit rather than cache by cache; behaviour is meant to be unchanged.

Evidence

project: { originalCwd: e, projectRoot: e, cwd: e },

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