I believe the F-Droid version is currently one patch behind. You can actually add https://archive.newpipe.net/fdroid/repo in F-Droid as a repository and you'll get the updates for NewPipe a lot faster.
I actually ended up going down a different route and created my own F-Droid repository for NewPipe and a couple other apps so I could get faster updates for them and I trust the upstream developers.
