Please note: this is my personal recommendation as a long time djay user and active member of this community. This is NOT an official statement from Algoriddim.
I’ve been beta testing 5.0 for weeks and it has definitely been worth the wait! The Neural Mix 2.0 sound quality is amazing, Crossfader Fusion is incredibly powerful and the Fluid Beatgrid system is simply unbelievable. Plus the final pre-release beta has been running rock solid for me in all the possible scenarios I could think of. You should definitely update and check it out 
However, as always, I suggest you perform a full system backup before updating. This way if you discover a bug that slipped through the vigorous testing process you will have a way to rollback to an earlier version.
