Moto E 2014 receives first Android 6.0 Marshmallow update via CM13 ROMGoogle

Moto E 2014 users are in for a special treat as the industrious CyanogenMod developers have unleashed their first Android 6.0 Marshmallow update for the handset via CyanogenMod 13 custom ROM. With Motorola unlikely to release the Marshmallow based official firmware for the handset anytime soon, the arrival of CM13 ROM gains precedence.
