It is exciting times with the new Android Lollipop (Android 5.0) release hitting a late model Android handset near you. It is apparently already available on Motorola Droid X and G and slated for Nexus phones on November 12th. There is a lot of interesting features in this release, from the switching on of the Android Runtime (ART) which enables ahead-of-time compilation of Android apps (instead of the more traditional Dalvik just-in-time compilation) to a new garbage collector.
ART was introduced in KitKat (Android 4.4) but it is now the default in Lollipop.
