There is no user interface to do that; in fact, it is usually
recommended to leave the old versions in place because that is how the
"Revert Configuration" feature is implemented, which allows you to roll
back to a previous set of plug-ins at any time.
Do you have a particular reason for wanting to lose the old versions?

Hi,
My 2-cents. :-)
It gets cluttered and takes up a lot of space over time. And I don't
care about reverting. If I did I would leave it there. I like to clean
up every once and a while.

Well, you can of course try that manually. But there is a certain amount
of danger in doing so. Some plug-ins can actually have more than one
version loaded at a time; depending on the expressed dependencies of
other plug-ins, removing an old version could cause problems for others.
For example, let's say that PluginA depends on version 1.0 of PluginZ.
Now let's say that you install version 2.0 of PluginZ and that PluginZ
is NOT a singleton plug-in. So Eclipse (OSGi, actually) is happy to load
both versions during runtime, one to satisfy the requirement of PluginA
and the other because it is the latest available version (maybe it is
required PluginB).
If you just bindly remove version 1.0 of PluginZ, PluginA will no longer
load (because it depended on PluginZ 1.0). See the problem? Because
plug-in interdependencies are so flexible and open-ended, it can be
tricky to know what is safe to remove and what to keep.
You can say "well I don't have that kind of scenario" and you might be
right, but it is almost impossible for a human to tell for sure, because
you'd have to know the transitive closure of all installed plug-in
dependencies. That is why p2 (and OSGi) are complex frameworks that
manage this stuff for you :-) Besides, p2 does not take too kindly to
changes made in plugins/ or features/ directories behind its back.
Bottom line, you can probably get away with removing old plug-in
versions manually for a while, but do it enough times and you will
probably eventually screw up your installation.

That's just it. I don't want to manually remove them. Going through the
directories myself and removing them by hand is dangerous. I want to
remove a feature through the Configuration Maintenance. Especially if
the feature is now disabled, which it would be if I added a new version
of the feature. I often have three, four, or more versions of a feature
as I go through work on the feature or download newer versions. This
causes a lot of clutter.
Of course the Configuration program needs to be smart enough to not
remove a plugin that is shared between an active and an inactive
feature. But if the plugin is only in the feature being removed, then it
should go away too.
