I've been looking at our high-priority regressions and have come to a
somewhat disturbing conclusion. Now, regressions aren't the whole story,
but based only on the regression data, it seems that 3.3 is in
substantially worse shape than either 3.2.x or 3.4, begging the question
of what the point of the 3.3 branch is. (Please read to the end before
you flame).
My two cents... Your analysis is interesting, indeed, but perhaps, done
now is not completely able to account for the amount of bugs
fixed for 3.3 and not for 3.2: I'm absolutely sure that *many* PR, about
bugs already fixed for 3.3 and not for 3.2, have been quickly closed,
because one more 3.2 release was not expected or were too difficult to
fix non invasively.
Comparing the size of the respective testsuites could be interesting, do
you agree?
There is also a good amount of new features! For instance I like so
much the improved C++ alias analysis.
As regards compile time performance, you are completely right,
unfortunately...
