Keep in mind that all of the changes have been backported into the
existing program versions which is a lot of work, and that someone
who understands the programs better than either of us decided that
effort was necessary.  Also, I think you are more likely to break
something with piecemeal updates compared to running exactly
the same mix of versions that have been tested together.

However, you might want to prepare some kind of backup/restore
strategy if the box is important.  There are many other things
more likely to break it than a minor version update.

The main issues that have been posted here involved a lockup
while yum was updating itself or its libraries and database.
There was some advice about updating these first, or using
'upd2date -u' instead, but I'm not sure which is best.
