I am going through the EasyApache process, and I'm presented with 4 different PHP minor versions to choose from; 5.2.9, 5.2.17, 5.3.8, 5.3.9. Currently 5.2.17 is being used. I see on the PHP site that 5.3.9 is the current stable version, but what is the difference between using 5.2.17 and 5.3.9? I'm not sure which one to choose between the two, and why one would be better than the other.
