Spent a little time trying to get the changelog plugin for eclipse working in my 3.0 installation on Windows. Adding the missing feature.properties file resolved a minor issue in "Manage Configuration". Still doesn't appear to work. The eclipse PDE error log doesn't help. I think it would help if the developer were to create an update site per FAQ 92 and put that up. Other than that not really sure why it doesn't show up in the preferences menu. No more time available right now to read up on how to setup plugin development and build it myself.
