AoE - Windows 10 release build or insider preivew

Will inclusion in the beta require current Windows 10 release build (Creators Update) or will those chosen be able to us Insider preview builds?

Since it will be available on the Windows Store, I guess it doesn’t matter, as long as you have Win10. Although, if you do playtest, it might be helpful to include your insider version of Win10 in a bug report if you encounter something.
