A couple days ago CM11 M1 was released to most Nexus devices, but we didn’t see nightly releases enabled for others. Well CyanogenMod has now enabled nightly releases of CM11 for every device that supports it!
Android 4.4.1 has also been merged into the code stream of CyanogenMod 11, so CM updates are up to date. Device maintainers for CM will perform these updates for their respective devices. You can find a full list of devices supported by hitting the source link.
