Just in case anyone is wondering, here's the listed changes:
This new version contains several bug fixes:
* Fixed antialiasing issues on DirectX 10
* Fixed pixelated graphics that occured on some systems
* Fixed crash on ATI 10.2 drivers
* Fixed issue with missing objective item when playing level "The Cure" for the second time
* Invert Mouse option for flying a plane is working now
* Copyprotection checks removed
I have the steam version, so I'll have to wait until steam applies the
patch.....
