Default [Q] CM11 nightlies or milestones, and trebuchet

I am using @jfbs CM11 013102014 and it has been very stable. I had to use greenify to get battery usage lower. I had trouble with CWM 6.0.4.7 but eventually got it to finish. My only trouble was that trebuchet FC'd after each boot, so I started using Nova launcher. Is this build based on a nightly or a milestone. I saw that M3 is out and was hoping that this build could be updated with M3 since it has a new trebuchet. Thank you to all the developers who are keeping this phone alive. It is so much more responsive now than Peach Sunrise was for me.
