The latest version of the Google Play Store is v6.7 and it should be hitting your Android device any day now. It is currently rolling out across many handsets. This is by no means an overhaul. Instead this is a pretty light update. This update is geared towards Beta apps.
You can now see the Beta status at the top of the app listing if you are enrolled in the beta program. You are now able to join or leave beta test from app listing at the bottom. You can even leave feedback for the developer of the beta app instead of posting comments on bugs in the public review. One really cool feature is that you are now able to view unreleased apps. You can download the latest play store from the link below.
