[Centos] Ok to update to 3.4

i get very little updates from yum, so i was wondering if it is ok
to go ahead and update to 3.4, being im running 3.3..

i run a minimal system...minus a few packages removed after install.

just didnt know about any possible security issues that would
come down for 3.3 if i have updated to 3.4..how would or would
i even need them....or will the upcoming security, bugs, etc.. be
strictly for 3.4?...what im trying to say is would i miss any
updates if i updated to 3.4, that are meant for 3.3?
