In a change from last year, Google officially plans to update the M Developer Preview at least twice before final release.
Speaking at the “What’s new in Android?” talk at Google I/O, Chet Haase of Google explained how the Android team plans to update the latest Developer Preview. Unlike the L Developer Preview last year, Google has an upgrade path set up to update the M Developer Preview once at the end of June and again at the end of July, each time integrating changes based on feedback from developers.
