Google recently started rolling out a new Android Market app with an over-hauled UI. While most people are still waiting for the new Market to be pushed to their phone, the smart ones already downloaded the APK from the Internet and installed it on their phone.
Now, Google has rolled out a minor update to the Android Market (v3.1.3) app, which includes two new features. First and foremost, the update brings some sort of integration with Google Plus, by including a +1 button in every apps page. Secondly, the update also brings a much needed and requested option to PIN lock new Android Market purchases. Other than that, the new update also shows when an app was last update, along with its download size.
The folks over at Droid-Life have already got their hands on the APK. I highly recommend Android handset owners to go ahead and download and install the APK from there. Otherwise, they will have to wait for quite a few weeks and maybe months for the OTA update to be hit their phone.
