Wanting to start out in networking

I've started a project that I will be using for Multiplayer. I'm at the point where I'd like to start the networking stuff. When I search "Unity Networking", I end up here: https://docs.unity3d.com/2020.1/Documentation/Manual/UNet.html. Next page is Multiplayer Overview, it says UNet is going to be depreciated so I don't want to use it and have to relearn a new system soon after. So, from there is a link to a post back in August 2018 (https://blogs.unity3d.com/2018/08/0...549.1108557586.1586242027-65672077.1586073088) and the last update on that page is April 11, 2019.

So should I just use UNet...? Or wait for this thing? Where can I get updated info from Unity on this?
Why mark something as 'going to be depreciated' if you're not going to give updates on it's replacement for a year or more? Does 'depreciated' have a time frame or does that just mean at some point but who knows when?

Sorry for sounding a bit ranty. I'm confused and get extra frustrated when I can't find resources.

Any advice is greatly appreciated.
