To avoid a repeat of the Lollipop disaster of November 2014, do we have confirmation from the developers whether it is safe to upgrade to Android Marshmallow (6.0)?
Marshmallow is being released today, October 5, 2015.
I do not work for D3. But I lived through the Lollipop disaster, and still went for it anyway. My Nexus 7 (2013) is now running Android 6.0 and MPQ works fine so far.
