Depends.  Most people do update as new updates come out. Doing 'yum
update' regularly will update to newer point releases automagically. 
Some people (for various reasons) don't regularly update their systems.

Look in /etc/issue

On a certain level there really isn't much difference from a general
admin POV -- it does not really make sense to go into a certain level of
detail (like specific version numbers). Basic functionallity is not
going to change from point version to point version.
