Android Marshmallow is the delicious new name of Google's forthcoming mobile operating system update the company announced today, replacing Android 5.0 Lollipop later this year.

Since Google IO 2015, it's been teased as just "Android M," which led to immense speculation as to what tasty treat the software could be named after.

It's always a snack of some sort, like Ice Cream Sandwich, Jelly Bean and KitKat before it. So everything was speculated, from milkshake, to muffin, to macadamia nut. Finally, the S'mores-friendly ingredient won out.

Here's what to expect

Truth be told, the naming convention doesn't actually change the features within Google's software. It's just a fun nickname other than saying Android 6.0 over and over again. It's more entertaining than, say, iOS 9.

Android Marshmallow is an incremental update slated to bring better memory management, easier app permissions and battery life-saving techniques. Lots of behind-the-scenes updates, for sure.

The biggest change is the debut of Google Now on Tap, which scans messages and webpages to predict what you want to Google before you actually reach for the search engine.

Android Pay, while not officially tied to the Android Marshmallow launch, is likely to arrive alongside this update and the Nexus 5 2015.

Android Marshmallow almost ready

The Alphabet company official launched Android 6.0 SDK this morning and announced that the Google Play Store is ready to accept developers Android Marshmallow apps.

Not soon enough? You're able to download Android 6.0 beta on four Nexus devices: Nexus 6, Nexus 5, Nexus Player and Nexus 9 tablet.
