We’ve been asked this question a lot since the announcement. So, we’ve decided to put together a quick response here, to be able to send people to.
Short answer: We don’t know yet.
Long(er) answer: We’d guess it’ll be this side of Christmas in a beta phase, with a more formal release after Christmas. We know absolutely nothing for certain, but this is the pattern for how previous big iterations of Shopify have been released. We’re doing our best to get as much information together for our retailers as possible — we’re on it!
