Hear, hear.  Stuck on 5.12 here.

Working on OS projects, commercial is not even an option, and resources 
(e.g. for testing/fixing on every new Qt release) are very limited 
(read: one person often does everything). E.g. testing one app on 5.14.1 
yielded 3 breaking Qt issues which had to be fixed upstream, and mostly 
didn't make it into .2 either. LTS (after like a .3 or so update) is the 
only way to go IMHO, the others are for testing/playing.

I'm so sick of "scheduled releases come hell or high water" in the 
programming world (in general, not just Qt).  The quality is (usually) 
crap.  Once upon a time this release quality was called 
Alpha/Beta/Preview/NFP (not for production).  Qt6 has literally been 
called as being "primarily" for testing/feedback.  That's a new major 
release now?  /further rant aborted

Sorry, I'm only passionate about it because I love what Qt does and I 
love when it does it well and consistently.  Everyone who's helped make 
it that way is my hero, thank you!
