If you've been patiently waiting for an Android 4.3-based CyanogenMod to arrive, prepare to get excited. Well, as long as you're the type that doesn't mind playing around with entirely experimental software, that is. On its official G+ page, the developers behind CyanogenMod say that not all devices are supported at the moment, but those that are not will have support added as time goes on. As this current update is considered to be a nightly, there's no bug reporting to take place (as always, this is to be used at your own risk).
Android 4.3, but sadly not CyanogenMod (yet)
Taking a look at the release page, we can see that support is actually quite good for the initial release. Notable devices include Google's Nexus 4, 7 and 10, Samsung's Galaxy S4, S3, Tab and Note, LG's Optimus G, HTC's One, Sony's Xperia Z and Motorola's Razr.
