I don't know whether this would be addressed in autoupdate, module system or API support, but hopefully I will give
enough information that you can reassign if needed.

We are using an AutoUpdate Center for our application.  Our users have complained that while they really like this
feature, there is no way for them to know what is in an update when we make one available.  The plugin manager simply
shows the information about the module and not specifically about the update.  There is currently no place to enter this
information, except for hacking it by appending information about each update to the OpenIDE-Module-Long-Description field.

I feel there should be an additional, but optional, field (or fields) that allows the developer to specify what specific
issues have been fixed by this update.  The plugin manager should show this information so the user can determine
whether or not to install the update.  

The operating system update managers for Windows, Mac OS X and Ubuntu Linux already work as I have described.
