yeah its change cause of user face the problems such as..below listed...
may be upcoming 0.7 release will not be compatible with our game but developers are trying there best for resovling gaming problems
-> Previously, a user could unplug the Oculus Rift and plug it back in without affecting the running app. With 0.7, the app won't continue to work unless the app recreates the shared textures.
-> OpenGL-based applications can judder if the application is configured to sync to the monitor's refresh rate instead of the refresh rate of the headset. To work around this, set the NVIDIA Vertical Sync control panel option to Use the 3D Application Setting or set the AMD control panel Wait for Vertical Refresh option to disabled.
-> If you receive the error message “HMD powered off, check HDMI connection” in the Oculus Configuration Utility with your headset and tracker correctly plugged in, make sure to update all of your system drivers (graphics, USB, and so on).
-> The mirror window might be blank and the headset might not work after installing the 0.7 runtime and the NVIDIA 355.83 driver (or later). To fix this issue, restart your computer with the headset plugged in. You should only have to do this once.
which are described problems are solve into this 0.7 and i hope its better than 0.5
