[Maya API] Supporting older versions of Maya (but still supporting VP2.0)

Hi all,

I’m adding Viewport 2.0 support to my plugs - does this mean I have to jettison support for pre VP2.0 versions of Maya?

Is there a clever way to manage this with Macros etc., or is this just a nightmare waiting to happen and I should drop support for versions of Maya that don’t support the VP2.0.

(Specifically Maya 2013.5 and below would stop being supported because I need to use a VP2.0 class that was only introduced with 2014).

Any tips/ advice appreciated.
Cheers,
Ian
