The Debian policy states that all software in stable stay at the same version, with patches backported from upstream. I'm not sure it really makes sense as a general policy; at least I'm pretty sure there could be exceptions for some packages with little dependancies, such as xscreensaver. Slackware 14.0 which is way older than Jessie and even older than Wheezy, comes with the latest, 5.34 xscreensaver in its update stream.
