CyanogenMod 11

Another milestone for the KitKat-based firmware

Visit the CyanogenMod download page and you'll see CM11 M3 builds are starting to roll off the servers. "M" builds are milestones along the development process as the KitKat-based CyanogenMod 11 approaches release candidate, and eventually stable status. So M-snapshot builds are supposed to be more stable than nightlies, but may still contain a few bugs.

At the time of writing we're seeing M3 builds for a wide range of devices including the Galaxy S4, HTC One and LG G2, along with many Nexus devices and legacy handsets. If you're already set up with a custom recovery on your device, you can hit up the source link to find the full list CM11 M3 builds ready for flashing.
