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.

More publishes treated as artifact-type instances

Artifacts

More publishes are now recognised as instances of an artifact type.

What

The check for whether a publish targets an instance of an artifact type no longer requires the session's types flag or a tracked file list. It now says yes if the file was created from a type, or if its frame URL parses as an artifact slug at all.

Evidence

createdFromType

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