Forgive me for being obtuse, but why do we care what number?
Correct – YOU don’t care – you just load and play.
But for anyone working on Development of Addons or Mods, knowing what got updated and when is of primary importance.
For anyone having problems with MSFS, knowing what got updated, and when, is also of help to them in determining what their issues are and if they have already been addressed.
So, YES, it does matter – to those it matters to
