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.

Agent, MCP and UI caches scoped per session

Under the hood
Useful2 Signal3
Session State

Agent, MCP and interface caches now die with the session instead of lingering in the process.

What

Agent definition loading, MCP connection, tool, resource and prompt caches, task-list watching, teammate mode snapshots, telemetry header caching, output path bindings, fleet roster and editor state, artifact stop latches and voice level smoothing all moved out of module globals. These caches are now discarded with their session rather than surviving for the life of the process.

Evidence

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