The Moto 360 (2015) is now receiving the latest Android Wear update update, containing support for Marshmallow features like Doze and more. According to the changelog posted by Motorola, the Moto 360 (2015) will support six new languages with the update as well, including Mandarin, Cantonese, Indonesian, Polish, Dutch and Thai.
Of course, the new update, which Google recently announced, also includes new wrist gestures, general performance improvements and support for granular app permissions. However, do keep in mind that, while the update does add support to Android Wear for speakers, Motorola has confirmed the Moto 360 does not pack a speaker on board.
In any case, Motorola says the update will be rolling out to users in phases over "the next few days," so you should expect to receive an update notification soon.
