Mertsch: There are some references to prior SDK (7.1) includes, but it's pretty much all 2015. EDIT: Though it looks like the boost libraries are still vc100, resulting in a target platform version of 8.1. I'll have to update boost and Lua sometime in the near future as it's been a while.
Hax: Yea, it automatically upgraded to the "Visual Studio 2015 - Windows XP (v140_xp)" platform toolset.
Neo: What are you referring to? Or do you mean, the Windows Start button in general (not having anything to do with S+)?
@Rob In my Win10 system, sometimes the Start button does not respond, updated to 2.8.5.0 problem goes away. :) I think this may be a rare small problem of a particular environment.
