How many people are using Visual Studio 2013?

The most recent JUCE-compatible version of the VST3 SDK that supports VS2013 is 3.6.7, which is now a couple of versions behind the latest (3.6.9). So, unless you’ve kept an old version of the SDK handy, compiling with VS2013 is going to be difficult. Is anyone unable to use a more modern version of Visual Studio? It would be nice to raise our minimum to VS2015 and have access to additional, more modern, C++ features within JUCE.
