Hopefully a quick BETA question

I am currently on the 20.04 BETA of Ubuntu MATE.

I am asking (to see if my assumption is correct) that if I do a normal update/upgrade once Ubuntu-Mate is officially released on the 23rd, that I will be up and running 20.04 proper at that time...

or am I wrong and I have to do some dist-upgrade thing?

A normal update/upgrade is all you will need to do.
