Concurrency Explorer 2.1 Released

The latest version of the Concurrency Explorer (ConcX) is available. It offers a significantly improved user interface, ability to load and run more than 100 birds, ability to save flocks of birds to an XML file and then reload them, and lots more. Get the source code from the SourceForge Subversion repository for now - a zip file of the source code will be available as soon as I figure out how to upload it.
