Upgrading can be painful?
"Upgrading can be painful in Linux thanks to potential dependency and configuration issues so waiting for the official guidance is a good plan."
Hugely less pain than Windows, where going NT 3.5x, NT4, Win2K, XP, Vista, Win7, Win8, Win10 is best with a fresh install.
I've tested 18.3 -> 19.3 which needs 18.3 to 19 first. Much slower than a fresh install and needs command line. But works. The 18.3 LTS maybe runs out this October, so no rush, though for existing 18.3 rather than a fresh install, likely it's 18.3 -> 19 ->19.3 -> 20.0
And then there are Mac OS upgrades. They've called all the versions since 2002 or 2003 change from Mac OS 9 version 10.<something> even though some are a greater change than Win2K to Win10 (like no 32 bit).
So rather unfair.
