I just wonder why it has to have a certain "label" for it to be used by everyone.
Lots of open source product are under continuous development. Sticking a label on it doesn't mean it's bug free. For some (look at Kohana), a version label doesn't mean anything, it's even something to fear, due to incompatibilities with previous versions.
CI is a very stable product, and it has to be otherwise it would break Ellislab's commercial products. Which for us developers is a plus, you can rely on it, and you don't have to go back to modify all your apps when a new version of the framework is released.
I'm using 2.0 for a long time now, without a single glitch.
