Is cm14 available for 3s prime (land) ???

I heard that source code of redmi 3s/prime is released. Is it true ? If so why isn't there any Nougat ROM available ?
becuz its Marshmallow based kernel source :3
If you check the ROMs section below, you find several ROMs based on Android 14.1. They are compiled by different developers and they are all unofficial.
Why "Ido" have fully working Nugat based custom rom's and "Land" not?
Where is the problem?

What's preventing LineageOS 15.1 to be officially released for athene?

There have been a good amount of 15.1 based ROMs posted here on xda, but that begs the question, what's stopping the official release? Apparently the only difference between unofficial and official releases is that the official is signed with the LOS key.
SEPolicy is required to be enforcing. Currently, it's on permissive.

Difference between Official and Unofficial ROM

Hi, just wanted to know the difference because beside many Custom ROMs some is Official and Unofficial.

Android 10

This thread is based on: https://forum.xda-developers.com/moto-maxx/general/android-9-pie-t3825923 (which is based on: https://forum.xda-developers.com/moto-maxx/general/oreo-8-0-t3660752)
But for Android 10 "Queen Cake", Who wants the new Android version on this phone?
@ChazzMatt wrote last year (edited for Android 10 "Queen Cake"):
It will take @fgl27 coding the current Motorola Marshmallow Quark kernel to Android 10 -- the same way he coded it to work for Nougat, Oreo and Pie.
Our previous CM dev @Skrilax_CZ did the original work back in early 2015, first coding Quark Motorola KitKat kernel to work with Lollipop. Then when Lollipop Motorola source code was finally published he used actual Lollipop kernel in the CM releases. Once CM had a kernel for Quark, THEN other devs could "port" ROMs and just plug in the CM kernel.
@fgl27 started doing dev work about this time and released his own "custom" kernel with more features to complement the "stock" CM kernel @Skrilax_CZ coded. You could use CM 12.1 ROM (with Lollipop 5.1) with CM kernel or even RR Lollipop with CM kernel -- or use those ROMs and install @fgl27's custom kernel. But all the ROMs uses the CM (now LOS) kernel as "stock" kernel. It's what makes ALL the Quark ROMs possible in the first place.
(For our Quark, even AOSP ROMs -- ALL ROMs -- use the CM kernel. They have to. There are no others. When SunShine unlocked the DROID TURBO bootloader @Skrilax_CZ re-coded the Quark CM kernel to also work with XT1254 -- otherwise these custom ROMs would NOT be compatible for all Quark. The kernel is the foundation.)
Then, when Motorola Marshmallow got released in late 2015, same thing. First a Lollipop kernel was coded to work with Marshmallow, then MONTHS later (July 2016, for XT1225) when Motorola released Marshmallow for Quark and then the kernel source code (September, October?) finally an actual Marshmallow kernel to work with Marshmallow. (Lollipop custom ROM for Quark beat official Motorola Lollipop and Quark Marshmallow custom ROM beat official Marshmallow by MONTHS.)
By this time @fgl27 had taken over all the kernel work, coding the basic "stock" kernel for all the Quark ROMs as well as his name-sake custom kernel.
When Nougat arrived, there was no official Nougat Quark kernel from Motorola -- so we had to keep using Marshmallow kernel. And @fgl27 did the work to let Nougat ROMs use that kernel.
When Oreo arrived, there was no official Oreo Quark kernel from Motorola -- so we had to keep using Marshmallow kernel. And @fgl27 did the work to let Oreo ROMs use that kernel.
When Pie arrived, there was no official Pie Quark kernel from Motorola -- so we had to keep using Marshmallow kernel. And @fgl27 did the work to let Pie ROMs use that kernel.
Will be the same thing with Android 10. But @fgl27 still has to code it to work smoothly with Android 10.
Also, there is no more CM. We actually have LOS as the "base". @fgl27 does not release official LOS ROMs, does release unofficial LOS ROMs, but that's where the device kernel files go that all devs pull from.
So, @fgl27 will use Marshmallow kernel in LOS Android 10 tree to make a stock kernel for all ROMs. At that point he will release an Android 10 ROM based on that work. (Right now he's the dev for both RR and LOS ROMs. This year he surprised us by releasing then-new Pie RR first, then LOS, where as he had been dev for Lollipop RR, Marshmallow RR and Mokee, Nougat RR and crDroid, Oreo RR, Pie RR and LOS, and RR was his favorite.)
@fgl27 will also probably release an advanced "standalone" custom kernel with more options, like he does now, but it's that base stock LOS kernel which is most important.
After he releases his Android 10 kernel work, then other Quark devs can use that stock LOS Android 10 Quark kernel to release their Android 10 ROMs.
The kernel will be the foundation of any Android 10 ROMs and it will all depend on @fgl27.
But don't pester him. It will be ready when it's ready.
__________
TLDR: @fgl27 is the man. He'll do the Android 10-compatible stock kernel first and then the first Android 10 custom ROM. Everyone else will then follow with other ROMs.
Thanks for the info.
until 2030 I have this working
