It appears another update for Google’s Android Market is starting to roll out today. This isn’t much of a change like we saw a few weeks ago but we do get a few very welcomed changed and additions to the market. What we have here are a few improvements as well as the introduction of the Google +1 button for apps and games.

The biggest change to the new market that is rolling out now and available to download (below) is Google added some new security features that users have been asking and hoping to see for a long time. We now have the same pin code lock/unlock security option as we’ve always had, but now another level placed on the Android market. Now you can choose to have a PIN for opening the Android market this way no one can purchase unwanted applications on your phone.

The new PIN code security is a great feature for those that have kids that love to accidentally buy apps, or that just don’t ask first. This is a great feature to have and something I’ve been waiting to see for a while now. For those that don’t want to wait for the new Market version 3.1.3 to hit your own device feel free to download it with the link below and start enjoying the new features right away.
