These 'Enterprise' versions have a very long update cycle during which
the included software is kept stable, generally by avoiding new
features and backporting bug and security fixes into the program
versions originally shipped. Within the major release numbers you can
usually expect 'yum update' not to break anything that was previously
running (with rare exceptions, of course). There are only a couple
of reasons that you would not choose the latest available. One is
that you have existing programs that won't run on the newest release
(which is why there is overlap), and another is that you want to avoid
the bugs that are unavoidable with the big changes that come in the
X.0 releases. But an installable 6.1 should be close and you can
already update to it with the CR repo.
The older releases still work, but using them means you are missing
out on years of development work and improvements in the software and
will have a much shorter update life going forward.
