This was said to me from a staff manager more than 2 years ago when I wanted to switch from a july weekly to a december stable (I never updated): "It's most likely a downgrade. We used the "12.6" version to give you the hint that Stables are normally months old in terms of code base, it doesn't matter if it was released after the particular Weekly (an exception would be if the Stable was released like a year after the Weekly you're using)."
So, understanding that in this case weekly 12.6 to stable 14 is an upgrade, I only want to know if I should to update to MIUI 13 first because sometimes it's better to go through major versions in-between in terms of compatibility.
