- Started Windows, Metro and Linux Platform-Plugins - Moved the RecordingSample to the Samples folder - Started two samples for using the graphics device in a WinForms and Wpf Editor - Refactorings in the AddIn-System - Moved the Window initialization-code to the Platform modules - Changed the License text in all code files which is now way smaller - Started ProjectConverter tool which converts all the projects and solution to the target configuration - Changed the SupportedPlatform names in the Resource files - Changed the WIN8 define to WINDOWSMETRO which is actually meant - Removed NLog and started our own Logger class - Many more stuff...
