Stable MIUI 7 Build Rolling Out To Mi 3 And Mi 4

Xiaomi has just released MIUI ROM that is based on Android 6.0 Marshmallow operating system and is available for download in China. The update is not the global version, and it can only be installed on the Chinese versions of Xiaomi Mi 3 or Mi 4 smartphones.

The official changelog is missing, but reportedly it addresses a few issues with Cortana, customized themes and other things. You can download the Recovery or Fastboot ROMs from Xiaomi's official forum, but make sure to follow steps so you don't end up with a broken phone.
