I'm pleased to announce 5.1.1 has been successfully merged and corresponding updates have been uploaded. Some other small under the hood changes (bugfixes, performance improvements) were also made by Khaon, Freak_97, DespairFactor and myself over this past week to various parts of the ROM so thanks to them for the hard work and dedication on fixing/improving the ROM!
There seems to be a lot of people not liking my custom GPS config or custom APNs so I've made a couple of flashable zips to revert back to stock components they are:

GPS Reverter

For those of you that don't know I use CyanogenMod APNs because they seem to support many more carriers than aosp by far.
For GPS I've been using GLONASS instead of the regular GPS settings. In my area GLONASS locks much faster. It is the Russian alternative to GPS and does not have as much traffic in my part of the world. I would assume that some people might not have as good of a lock in the eastern hemisphere because there would be more traffic on GLONASS there (because Russians would be using it too). So if you happen to be one of those unlucky people that can't get a lock on GLONASS revert back to stock GPS using the file above and everything should work fine.
Note: These links are also on the OP for future newcomers.
Enjoy the updates!
