Update: The Nexus 7 2013 build (codename "Flo") has now been posted. It's the first official CM build for the new Nexus 7.
ROM addicts, the time has come. The CyanogenMod team has been working diligently on version 10.2 of the popular ROM family, the Android Jelly Bean 4.3 update. Tonight the first batch of nightlies are being posted to the download page, Get.CM. There are only a few devices with updated builds at the moment, but that should change as the night progresses.
