According to Phandroid, the CyanogenMod is now stable on the 10.2 version. The 10.2 is based on Android 4.3 Jelly Bean and therefore it is an important step for those who follow this firmware [you can learn more about CyanogenMod here] because it means they will not only focus in the KitKat 4.4 version of Android but also because it is now ready for the public usage.
CyanogenMod based on Android 4.4 for when?
According to some comments online, we can expect a version for the Kitkat around March 2014. The team states this will be called Cyanogen 11. Even so the 10.2 version will still be supported in the future with bug and errors correction and new security patches.
