- Added an observable sequence which starts producing elements form a specified asynchronous Subscribe method when first subscriber subscribes, and stops producing elements when all subscribers cancel their subscription.
- SpecificVersion is set to 'false' for RX's assemblies
- Checking the renderer status is optimized to reduce number of requests to a device. Now it periodically checks the renderer status only in case if anyone interested in it, i.e. subscribed to a specific events.
