Routing-test ospf general options

Has anyone else noticed the lack of the general options in ospf? I can’t figure out how to do things like redistribute default route, etc. The button in Winbox is gone and nothing’s showing up in the CLI. I’m not sure how far back this goes, but I know that I just upgraded to 3.20 hoping to find it again. Alas, it isn’t there.

The general options settings are still available but it had been moved to the “instances” tab. You can add as many instances as you require and then apply this instance to specific OSPF Areas.

Where is documentation on how to use this (I haven’t actually looked at it yet), or even OSPF in 3.x in general?

Is the test version only CLI and not in Winbox?
