Generally speaking, security updates are ongoing and point releases are the 
accumulation of the security updates plus bugfixes at different points in time 
with the less critical bugfixes all released at once.  But, the reason it is an 
'enterprise' release is that updates within a major release are not supposed to 
   change behavior or compatibility in ways that will break programs you are 
running.  There have been some rare exceptions but unless you know something the 
team preparing the updates doesn't, you are probably better off just staying up 
to date.
