I understand the whining, bugs that get released are embarrassing.  But 
when I read the NEWS, I can see that both the NEW FEATURES and BUG FIXES 
sections of x.y.0 releases tend to be much longer than the BUG FIXES 
sections in patch releases.  That seems to indicate that things are 
working reasonably well.

For a really rough measure, just counting bullet points:

R 4.0.0:  65 new features, 55 bug fixes

R 3.6.3:  1 new feature, 7 bug fixes

R 3.6.2:  2 new features, 21 bug fixes

R 3.6.1:  0 new features, 16 bug fixes

R 3.6.0:  72 new features, 62 bug fixes

You can get these numbers programmatically:

R4 <- news()
table(R4$Category)

R3 <- news(package = "R-3")
table(R3$Version, R3$Category)
