I've been fielding a few questions about this over the past few days.
Firstly, if you want to run a real tube I suggest buying
MechBunny
Secondly the update for TubeX is really intended to help keep existing users going as hosts move to PHP 7 and for anyone wanting to start an embedded tube and have the technical skills to install it.
If anyone has any questions feel free to ask here or contact me directly.
