Sony Xperia Z gets the Android 4.4 KitKat treatment in a stable ROM release

It is a stable ROM and most everything seems to be working, but since the mod is based on AOSP, there's no root or recovery here yet. The only minor quibbles are that you have to reboot twice for the Calendar to start syncing, and hit the home button when choosing a mobile network manually. Hit the source link if you are interested in installing it on your Xperia Z.
