Who should upgrade?
If you are doing development with GIF or JPEG libraries
you should upgrade. If you will be using RPMs from
the Red Hat FTP contrib site or any non Red Hat, Inc. that uses GIF or JPEG libraries you should upgrade. For
example, if you wish to follow GNOME development (and
want to install the upcoming GNOME 0.20 RPMs) you should
upgrade.
If you are running a pure server platform that does not
do any processing of GIF or JPEG images you probably do
not need to upgrade.
