They said in the newsletter that we (Standard editioners) would be emailed a coupon code but I haven't got anything. I tried via the upgrade route and I got an email from Xsolla to upgrade normally by just paying the rest of the sum. Did I miss something?
The coupons haven't been sent out yet — we're currently undergoing procedures to make sure the delivery of the coupons to all Standard Edition buyers goes well. They'll arrive before the end of June at the latest; should be sooner than that.
