In SDK beta3, there are API changes in the Processing* framework support. As we continuously evolve the SDK features and understand the developer needs, there might be additional changes. The SDK binary compatibility is maintained at the C++ libraries level. For Processing, Unity*, and C# applications, the developers should package their applications with all the supporting libraries to maintain compatibility, as described in the SDK Developer Guide at http://software.intel.com/sites/landingpage/perceptual_computing/documentation/html/.
