I did try searching for this but didn't find anything.
I've been following some tutorials for Rigging and have seen a lot of videos showing Armature Templates available from the Armature sub option see attached. On the version of blender I'm using 2.8 Beta Win 10 64 bit (23 April 19) I have no options to select anything. Only the Armature menu heading is from the ADD option which when selected provides a single bone.
Have these other options gone now or do I need to configure something within blender?
