Fabien Potencier (of the Symfony framework) has a new post to his site talking about a philosophy that the Symfony framework community should work towards, providing stability over features.
Long story short: in the coming months, the Symfony core contributors should focus their efforts toward stabilizing the existing features instead of working on new ones. At this point, backward compatibility and stability are more important than everything else.
He highlights some of the points that come along with this effort including less refactoring for the sake of refactoring, fixing more bugs/edge cases and writing more tests/documentation. He gets into some of the specifics of this kind of thinking and points out the things that can and can't be changed during this time. He talks more about stability and suggests that not only can it help enhance performance but it could also help motivate more projects/corporate users to start using the framework.
