You could wait a week and use stable 2.4.3 version. And you can start with 2.4.3rc, it is stable enough.

You should also know, that minor versions (2.4.x) of OpenCV are binary compatible: http://upstream-tracker.org/versions/opencv.html . That means that you shouldn't even recompile your application while switching from one "minor" version to another. And of course you shouldn't change anything in your sources. But 2.5 version will introduce API changes, as the Git master branch right now.

You may use 2.4.2 the most stable version. It depends on your kind of project.
You should check the release notes to see whether newer versions, have feature that will affect your project as well.
One of the most important updates in newer versions is for high performance computing using GPU Cuda and OpenCL.
