I have 2013 professional edition with original key of product and I like this version. Starting 4.11 I guess just do in VSS 2015 and I don’t understand the reasons, but it’s cool when you do a new tools allow old things continue working.
One thing that i hate in google tools is this each new version of a tool the oldest things depreciated sample this is: Android Studio and Python.
Please don’t follow this way.
My humble opinion.
