LineageOS is based on AOSP with contributions from many people within the Android community. It can be used without any need to have any Google application installed. If needed you can install any GApps package available for T.

LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway.

The source code for LineageOS is available at GitHub. And if you would like to contribute to Lineage OS, please visit Gerrit Code Review. You can also view the Changelog for a full list of changes & features.

Reporting bugs:

Bug reports without a complete description of the issue and a logcat will be ignored!

DO NOT Report bugs if you're running a custom kernel or you installed Xposed

Grab a logcat right after the problem has occurred. (Please include at least a few pages of the log, not just the last few lines, unless you know what you're doing.)

If it is a random reboot, grab /sys/fs/pstore/console-ramoops and /sys/fs/pstore/dmesg-ramoops-0. (Do not bother getting a logcat unless you can get it just before the reboot. A logcat after a reboot is useless)
