Google dropped a few bits of news today. Android M is now officially android marshmallow - and with that announcement we also have another developer preview available at the link below. *Remember, these are previews and typically have bugs that are worked out before the final release. Nice for a sneak peak at whats to come, but usually not daily driver worthy.*
