Artifacts can now be published by anyone with write access, not only the owner
What
Publishing or writing to an artifact you don't own is now allowed without an extra prompt, as long as you have writer or owner access to it, the change isn't going public, and the artifact wasn't shared with you via another organization. This is tracked through new canWrite and invitedByOtherOrg fields, and the artifact URL tool's description was updated to say an artifact must be one the person owns or was given edit access to (shown as 'writer').
Why
This lets collaborators who've been given write access to an artifact actually publish changes to it, instead of that ability being limited to the original owner.
