What

Uploading or listing an asset now tells the model to reference it from the page by its url verbatim, rather than as a relative url. The phrase "relative url" is gone from the build, so the url handed back is what must be pasted in.

Details
  • The same text explains that an asset is read or deleted by the id following _blob/ in its url.
  • Applies to every artifact asset upload and listing; no setting involved.
Evidence

reference one from the page by its url verbatim, read or delete it by the id after "_blob/":

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