+### Note 
+Some of the APIs used are in beta. Others are GA. As the beta's become GA, I will remove the 'hard-coded' use of their 
+beta counterparts. Meantime, please DO NOT specify a beta version of an API should you wish to choose a specific 
+version. It is recommended at this time that you allow the default version to be used.
