Nothing major this build, mainly a series of smaller things which should generally improve usability and alleviate some annoyances that had been noted on the forum. We're well aware of the need for the Families system now so that's definitely next up (for real this time). This is a lot of work so there may be a long gap with no new releases at some point, depending on where it fits in to the schedule.
Tom's been steadily improving the Arcade since its release - you can now embed games using a little code on the game page. Now you can share games on your own websites! Have a go and see how it works for you!
