Ah, so you think you have to choose between those two?

Yes there are.

Every 0.x.0 and 1.x.0 release was also a branch point/root for a
stable tree up to 1.1.y.  This allowed concurrent development of
bug-fixes 1.x.1 and new developments on 1.x+1
I named the branch STABLE-1_X, and the branch root tag STABLE-1_X_0
We have seven bugfix only releases in 0.6, 0.7 and 1.1.

In other words:
- we can make a STABLE-1_4 branch that allows bug fixes towards 1.4.1.
 -we can word on HEAD for 1.5.

You don't have to choose then, both developments can continue.
