What probably matters to youSection of the release
What
Paths equal to or under data/users/me in the artifact database tool are now rewritten to data/users/<your id>/.... The id is fetched by a new "whoami" request with a 15 second timeout, cached per account, with concurrent lookups sharing one request.
Details
New error text covers a malformed identity response and a failure to declare the capability
The cache means one lookup per account per session rather than one per path
Evidence
data/users/me
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
