I want to make some minor changes in the DockSiteRegionBehavior to fit our requirements and looking for the source code of the Docking.Interop project. On http://actipro.codeplex.com I only found the version 2012.1. Why is the new version not available? What are the differences between 2012.1 and 2012.2.574? Currently I use the adapted the source of the old version and I think it's working.
Thanks in advance.
