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.

Config writers gained an in-memory short circuit

Not switched on
Useful2 Signal3
Internals

Config saves can be kept in memory instead of written to disk.

A "memory" writer mode short-circuits config writes; nothing in the build sets it.

What

The project and global config writers now return before writing to disk when an in-memory mode is set, and deleting a project config has a matching in-memory path. A setter turns the mode on with the value "memory".

Evidence

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