What probably matters to youSection of the release
Unclear Only the setting's description is confirmed to have changed, not the code that applies it.
What
The gatewayUrl setting pre-fills the address of a gateway to log in through. It applies when forceLoginMethod is set to "gateway". Its description has changed:
It is honoured from managed settings, the ones an administrator controls.
On a machine with no managed settings, it is now also honoured from your own user settings.
It is still ignored in project, local, command-line flag and remotely delivered settings.
The setting is also no longer described as an auto-connect.
Why
On a personal machine with no administrator, you can now set the gateway address yourself instead of needing managed settings.
