There's a new version of the Google Play Store rolling out to users right now, but it doesn't appear to be brimming with any big, bold new features. However, there are some interesting bits and pieces floating around inside of the APK that point to some of the things we can look forward to in the future. A teardown of v6.9 points to a built-in app streaming interface and a custom purchasing experience for Cardboard. There are also quite a few odd little tweaks to various other things. We're still looking for more changes, so hit the download link below and take a look around for yourself.
