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.
Scratch files are written per session instead of one shared directory

Sessions
Scratch files now live in a per-session directory so concurrent sessions don't collide.
What's wrong with this entry?
Anonymous. No account, no email.
What
Background task output links, project documentation copies and fetched project files now go into a directory derived from the current session rather than one global temp directory, so concurrent sessions do not share scratch space.
Details
Affects files named project-doc-.txt and project-file- as well as task output.
The session directory is created on demand at write time.
Evidence
project-doc-
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
