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.

Module-level caches became resettable session state

Under the hood
Useful2 Signal2
Session State

Long-lived caches now clear per session or fork rather than lasting the whole process.

What

Dozens of long-lived caches now hang off a session state object with a reset method, so they can be cleared per session or fork instead of living for the whole process.

Details
  • Covers the install-latest in-flight promise, task-list leader name, artifact live, auto-react and wake registries, clipboard probe results, gitignore pattern compile caches, the plugin activity ring buffer, marketplace tip caches, the plugin flag cache, session title and agent-name events, and the background-result-seen channel.
