Hi!
The methods are added to VMStatus class and delegated to VM class. The old methods are marked as deprecated and we plan to get rid of them soon.
I highly recommend to use these methods everywhere and never to compare to VMStatus constants directly. There are methods to check for individual states and for meaningful sets - using them makes the code much more clear and understandable and it was the goal.
If you cannot find a method that fits your needs, feel free to contact me, we can add it.
