It is definitely not available yet. Please be patient, and it will become available.
As for “new” items not working if your devkit is behind, this is simply not true. As long as you set your mod up correctly, those new items will be available to you. In my mod, new dinos spawn before the update is given, and new items can be spawned using the “giveitem” or “giveitemnum” commands. You just have to make sure that everything is set up correctly and that it is setup to work with future updates.
