Will it be required to flash latest firmware for the official lineage builds?

Note : I am currently on MIUI 7.7.13 Beta. I haven't flashed any unofficial build ( coz i recently unlocked my device)
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] Firipu:
Clean flash needed for the official build? Or can I just flash it over the last unofficial?
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] shyam.kumar1009:
Clean flash will be highly recommended.

*.Once the official build hits, DL it and boot to TWRP, wipe everything except internal storage / SD card, flash rom, gapps and root zip, reboot.

Security patches and any changes (feature additions and fixes) made to the Lineage source by the Lineage team.

Huge thanks to [MENTION=6070905]abhishek987[/MENTION] and [MENTION=7737930]highwaystar_ru[/MENTION] and others who contributed to this!!!thanks a ton guys :D

NOTE THAT NO VOLTE ICON AND OMS AVAILABLE ON OFFICIAL BUILDS! :svetius:

How to install?

DL Rom, gapps and su addon (if you want root)

Boot to twrp, and make a complete wipe (advanced wipe > choose wipe cache, dalvik, data, system)

Locate Rom.zip and flash it, followed by Gapps and su addon

Flash firmware provided in the OP if you're coming from marshmallow based MIUI before the Rom installation

Again, clean installation is always recommended!

Official is compiled and maintained by a team member or maintainer from the group who developed the ROM in general.

It has some blobs related to modem etc. It's only required when transitioning from MM to Nougat.

Disappointing or not, it's not possible. Someone has quoted some posts before that he has tried restoring backup but it would constantly crash and clearing dalvik/cache too doesn't yield anything.

YES, it's from MIUI N and contains firmware for N. Flashing this just makes sure you don't have issues with improper firmware because people never bothered to flash it. Now the ROMs check for it at install. So sacrifice extra 5 seconds in TWRP and flash it.
