CyanogenMod is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. You will need to provide your own Google Applications package (gapps). CyanogenMod does still include various hardware-specific code, which is also slowly being open-sourced anyway.

All the source code for CyanogenMod is available in the CyanogenMod Github repo. And if you would like to contribute to CyanogenMod, please visit our Gerrit Code Review. Your changelog is whatever was merged into gerrit.

Welcome everyone! I am now the new Official Cyanogenmod klimtwifi maintainer

Known Issues
MHL has no sound and wrong colors
If you map MENU to a capacitive key (no matter if key itself or "long press", it will not work - workaround: do not map MENU to anything at all, then the apps are forced to show action overflow menu (aks 3 dot menu) - works on some apps (i.e. bootloguptime) on others not.
Some minor crackling when using bt-audio the same time as 2.4GHz wlan (5Ghz wlan is issue free).
YOU tell us...

I am curious, I have read up that 5.1.1 has native USB Audio built in, but most everyone has been using 5.0.x and having to use an app to play music through a USB DAC, but when it comes to any other sound generating app such as YouTube, a video player, etc audio is routed directly through the tablet. I have a high end DAC but I don't trust using it for what I'm planning since it's a 5.1 Asus Xonar. I wouldn't trust it not working to judge another. I know my S6 that only works with the specific music apps, unable to test the T700 right now, sorry for the story, just wanted to know if there are USB Audio Drivers built into cm12.1

i was just browsing. the cpu was mostly below 1000 mhz. This is a bit disapointing since it was around 10-15% per hour with the original rom.

I am working on moving to a new gpu driver that seems to be giving a much better battery life under heavier load.

baterie drain is around 15% per hour while surfing with 20% brightness. What I'm wondering is that if the tablet is in deep sleep it show no batterie drain ( 0% in 20h with wifi off). But after I start the tablet again the batterie goes kinda fast down to a certain point and stops again. This phenomen was present during all previous nightys. Lets see how it is with the new build.

Crackling through BT while on 2.4 Wifi is known but I am also having loss of sound synchronization on YouTube. No issues if wired headset is used.
