As everyone expected, Android M was officially unveiled at the annual Google I/O conference today, where the company promised hundreds of new features for the next version of its mobile operating system. Confirming previous rumors, the company revealed that Android’s app permission system is being reworked to give users more control of the data they’re sharing with apps. That’s just one of the many things that Google is changing up and improving with Android M, but there’s simply too much to put into a single article.
