Updated SU 2018

I have just been advised that there is a new version of SU 2018 that I can install. That puts me in a quandary. The new version of SU 2019 must be imminent if past years are anything to go by. So I am not sure whether to bother with a new version of the old software. Or does this suggest that 2019 may not be here as soon as we all expect??

Ed: Isn’t it an update, not a new version?
