Then thats your problem but don't complain about it if you don't 
actually use it... if you did you'd realise the changes are more minor 
than you make out. This is 2.4 to 2.5, not 2.4.1 to 2.4.2, so the API is 
allowed to change.

Because as I said above some programs can work with either version, some 
require a particular one ... and you don't want the user to change the 
source code.
Anyway if its not important to you then thats fine but there are 
situations in which version selection is important...
