Hey guys,

Great news! I'll be adding audio support for the next version (v5) that will enable you to easily connect a microphone and speaker to the shield via a four-pin header so you can call your pet while away from home?!?! And all that stuff within the same shield dimensions!

Unfortunately adding audio support meant taking away the extra I2C header that I had included previously, but I'm not sure how many people would be using the extra header anyway, so I don't feel all that bad.  :)
