CentOS docs - Jul 2012 - release notes for 6.3

Hi people

     I have created the RN6.3 page in the wiki, so as to be sure that we 
do not forget which packages from 6.2/updates are newer than 6.3/media.
     Unfortunately the wiki engine did not allow me to copy/paste the 
acl line from the RN/6.2 page so if you have issues because of that 
we'll need an admin to fix the problem.


     Regards
