LineageOS (as well as CM did until December 2016) still maintains the cm11.0 / 4.4.4 sources to keep pace with 'The Android Security Bulletin' (ASB).
Patches for CVE security issues are released at least once a month to the Android Open Source Project (AOSP) repository.
Patches for Android 4.4.4 are not provided by ASB anymore.
This means, security wise Android 4.4.4 is formally dead.
Nevertheless there are a few enthusiasts, still backporting security patches from recent Android versions to 4.4.4.
You should know, such backports are no formal ASB security patches.
Therefore the security patch level of this ROM is named: Unofficial Security Backport "April 2019".
Despite of implementing these security patches by the LineageOS team to its own repository https://github.com/LineageOS, LineageOS does not provide cm11 builds anymore.
Since I personally like 4.4.4. more than later versions, I build it myself unofficially and would like to share it.
The build is made from LineageOS "Branch: cm-11.0" PLUS ASB security patches, even if they are not yet approved by LineageOS.
The main goal of this ROM is to provide up to date builds in terms of ASB security patches, not development.

The stock browser is removed from this ROM due to severe security issues, which cannot get fixed.
Get a state of art browser (like firefox) from play store instead.
xposed not supported - a fix is provided by Lenny Bard, see instructions at post here.
