Google Play finally rolled out the ability for apps to have delta updates. This is actually really cool because it saves massive amounts of data. The play store analyzes the newer version and the previous version, figures out what part of the code has changed and applies that small amount of code as a patch instead of having to re-download the whole app over again. This is especially awesome for graphic intensive games such as SHADOWGUN (which is 100 mb by the way), because you don’t have to download 100 mb for a patch that is only 5 mb. Video is embedded below.
