What probably matters to youSection of the release
What
The settings description for the cloud gateway login URL no longer marks itself internal and now states that the value is read only from admin-controlled managed settings (MDM, managed-settings.json, or the policy helper) and ignored if it appears in user, project, or remotely delivered settings.
Evidence
Honored only from admin-controlled managed settings (MDM / managed-settings.json / policy helper); ignored in user, project, and remote-delivered settings.
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
