- <b>OpenFlipper 2.0 ( 2014/02/13 , 18180 )</b>
     - <b>Significant interface changes and Bugfixes</b>
         - Interface: Don't use allow addEmpty in FileInterface anymore (deprecated long time ago and basically unused! The type plugins handle this signal anyway.)
         - Interface: Renamed and extended functions to block scenegraph updates. OpenFlipper::Options::loadingSettings replaced by 
             - sceneGraphUpdatesBlocked()
             - blockSceneGraphUpdates()
             - unblockSceneGraphUpdates()
         - Bugfix: Fixed undirected shooting function returning wrong nearest triangle (was always the one with the most negative distance) in BSP
         - Interface: RayCollision is now a sorted vector conbining standard pairs of the hit handles and their distance to the hit
         - Interface: Render Interface: Implemented capabilities check for renderer interface
         - Interface: ACG, Renamed the basecolor functions in the core to defaultColor
         - Bugfix: Emit object updates for all objects in scene, if -1 is given as updated object. (Should not be used, as it is very slow for a large object count!)
         - Logic: if an object gets deleted, no updatedObject (-1) signal will be emitted now. Use the objectDeleted slot from LoadSaveInterface.
         - Build: Default to relesae build type by default 
         - Interface: Changed selection interface the qicons have been replaced by QString. The path to the icon has to be given now This avoids the problem of qpixmap creation in the selection plugins, when no gui is present Added deprecation warning, to informa about deprecated plugin interface usage
         - Interface: Don't emit updatedObject(-1) anymore if an object gets deleted. Use the slot objectDeleted from LoadSaveInterface instead.
