Xiaomi launched MIUI 12 in China almost a month ago. The company has announced the global rollout of MIUI 12 today along with update schedule for rollout of the same on a number of Xiaomi Devices. This basically confirms the different Xiaomi smartphone models that will be receiving the MIUI 12 upgrade. 
Unfortunately, it also confirms that some of the old devices such as Redmi Note 4 won’t be getting the update. MIUI 11 update for Note 4 was rolled out around November last year and probably will be the last major upgrade that the device had received.
