You'll notice
Artifact 'update in place' now works for editors given write access, not just the owner
What
When updating an artifact in place using its url, the tool used to require that the artifact belong to the user. Now it also accepts an artifact the user was merely given edit access to, shown internally as the 'writer' role.
Why
This means artifacts shared with edit permission can be updated by the person they were shared with, not only by whoever originally created them.
