After the Moto G was unveiled last week, invites to Moto X users started rolling out and everyone assumed it was for Android 4.4. It has now been confirmed that this is the case, and Motorola released the changelog for the update. Kind of hard to believe that Verizon will be the first to get the update since they have a knack for being the last in line for anything, but maybe they turned over a new leaf. If you want to check out the official changelog for the update, it is provided below for you.
