This build adds support for statistics and leaderboards in Xbox Live. You can now submit Xbox One games with leaderboards to the Xbox Live Creators Program! We are excited to hear back from anyone who publishes to Xbox One this way - please let us know how it goes for you if you try.
In addition to that we've got a batch of bug fixes. In several cases we've back-ported fixes from issues first reported in Construct 3 - if we make a fix to C3 which we can back-port to C2, then we will. We've also fixed a particularly annoying issue with exporting to Cordova that first cropped up in r246. If you previously saw an error message about config.xml, that should be fixed now.
