The custom based ROM now offers Android 4.4.2 Kitkat which runs flawlessly and can be used as a daily driver for that matter.
Well there is still a problems to update the same via OTA that Cyanogen Mod servers provide. If you are blindly updating Cyanogen Mod 10.2 Nightlies to Cyanogen Mod 11 Nightlies, then you will have to face an error during installations that probably may get cancelled half way leaving a continuously booting device behind.
