Android M is Marshmallow!
Along with the name, Google is releasing a final developer preview of Marshmallow, and SDKs for Android 6.0 — Marshmallow’s official build number. Developers can also start publishing apps to Google Play that have all the latest APIs (currently level 23).
Developers are encouraged to test the new permission model for app updates and installs, and official support for fingerprint sensors and a power saving mode are also available.
The final APIs are incremental; there’s nothing significantly different from the last preview build, says Google. Developers can also take advantage of Google’s new beta testing program for Marshmallow-ready apps published to Google Play.
