CM is no longer supplying change logs for 5.1. At least I cannot find then. For that reason, I will not be making any more builds. I will leave these available for a few months.
CM 12.1 compiled from source with Uber Toolchain 4.8. Any issues that are in official CM are present here. I was looking for an updated LP rom, and most have switched to MM, so I did this and learned how to build in the process.
I will try to update every weekend. You should know how to install a ROM, i am not a developer nor can I include any suggestions or fixes.
DO NOT USE CMUPDATER - it will install CM 13 on your device. I suggest you turn it off.
