Which Beta should I download?

I currently have a filserver VM running Windows Server 2012 R2 Standard, and its running DrivePool 2.2.0.734. I had some weird issue, and Christopher (I think) said I should grab that one. That solved the problem and its been running file ever since

Now I re-building my fileserver VM with Windows Server 2016 Standard. Should I grab the same Beta or should I grab a newer one?

Thanks!
