Re: Cash 22
"the latest version of LineageOS"
Too right! I bought an Honor 5x and Huawei were bragging about how great they were going to be with updates and how the 1st update was in the pipeline before the phone even shipped. Today it's android security patch level is more than 12 months old - useless bastards no honor/Huawei again for me.
My oldest phone a 1st gen Moto G is running 7.1.2 (LineageOS) with a patch level less than 12 days old.
That said LineageOS isn't usually rooted by default and you need an unlocked bootloader/recovery to install an OS not root.
