LineageOS 15.1 is a free, community built, aftermarket firmware distribution of Android 8.1 (Oreo), which is designed to increase performance and reliability over stock Android for your device.

Code:
#include <std_disclaimer.h>

/*
 * Your warranty is now void.
 *
 * We are not responsible for bricked devices, dead SD cards,
 * thermonuclear war, or you getting fired because the alarm app failed. Please
 * do some research if you have any concerns about features included in this ROM
 * before flashing it! YOU are choosing to make these modifications, and if
 * you point the finger at us for messing up your device, we will laugh at you.
 *

LineageOS 15.1 is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. You will need to provide your own Google Applications package (gapps). LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway.

All the source code for LineageOS 15.1 is available in the LineageOS Github repo. And if you would like to contribute to LineageOS, please visit our Gerrit Code Review. Your changelog is whatever was merged into gerrit.

Bug reporting:

Before the report make sure that you've installed the latest build of the ROM.
Explain the bug in details and, if possible, methods to reproduce it.
For most issues, you should attach the logcat.
Random reboots? Please upload last_kmsg immediately after the kernel crash.

Note: I will only be providing builds once every month and when new security patches come in. I don't have enough time to be making them every week. Latest build provided should have the June 2019 security patches. These builds should be pure Lineage based builds and they have not been tested so if you could give me feedback i would appreciate it. Please download the latest version of ARM64 OpenGapps and flash along with the ROM to be able to use the play store and other google related services. Also make sure you are using latest twrp recovery. If you want to root i recommend flashing and using Magisk 19.4. Enjoy and i hope you appreciate my pure Lineage 15.1 Unofficial builds for Flounder.

Thank you so much for your kind words it really mean a lot to me I always love to at least try to make new ROMs for you all. Unfortunately i took apart my nexus 9 and i ended up breaking the motherboard so i can't test these ROMS but hopefully soon i will try to fix my nexus 9 and have it working again i just don't know when. So if you could test my ROMs and give me feedback i would appreciate it

I just made crdroid oreo for flounder if you could test it would mean a lot to me

This ROM encrypted the device and asking for a password in the TWRP after a BL.

Thank-you so much for this ROM. I really wanted to get a little more lifetime out of my N9 while I wait for something suitable to replace it, and Android 7 just wasn't cutting it any longer when all my other devices have moved on.

FYI, I have the LTE version and so far I've had no issues, except for one shutdown while the tablet was idle overnight, though at first I forgot to wipe the system partition before applying the ROM and it just boot-looped.

I did notice that after using it for about an hour the front near the top or left (depending on how you hold it), was extremely hot - I'd been watching some YouTube videos but before this ROM it had never been as hot as this time.

Still, please keep up the updates for as long as you can.
