The CyanogenMod Team continue their work on the CM10.1 ROMs which will be the first ones that will be based on Android 4.2 Jelly Bean firmware.
At the moment there is no official release date for the first Nightlies but it should happen until this months ends. It will include all the features and functions of Android 4.2 and the ‘mr1-staging’ and it is listed in github right now. Some basic functions of CM 10.1 have already been added to ‘mr1’ and there should be more added in the next weeks.
CyanogenMod 10.1 is build-able and it includes support for the Nexus 4 also. Externals of CM are set and then CM build scriptage are included and fully working. The rest of the features will be added when all errors and incompatibilities with the Android 4.2 will be repaired. Its current status announcement has been made for developers so that they can work on future ROM releases.
The CM team says that all Android 4.2 AOSP devices will also be supported by CyanogenMod 10.1 nightlies. Developers can use the ‘build-able’ files and create an unofficial Mako version which will be incomplete, though that these will be fixed with future releases.
The release of the CM10.1 nightlies will not be available too soon and some new CM-based functions will be available, such as the Quick Settings and Toggles for the Notifications panel. More info about the next release of CyanogenMod team nightlies build should be launched in the next coming weeks on their Google Plus web page.
The CyanogenMod 10.1 will include the CM Updater, File Manager, Apollo media player and all their other new features that should be updated in time with the final and first release of the Nightly builds of CM10.1. Most of these can also be found on Google’s Play Store web site.
