The one in the description above is the lastest. But note, that is the name of the deform bones only. Not the control or other auxiliary bones that Rigify uses while in blender. 

So when you export, with deform bones only, and import your model into Godot, you will see the bones listed above. But in blender, you will only see those bones if you really dig into the rig, because they're SUPER nested in their hierarchy, and even if you enable deform bones to be visible (because they are hidden in blender by default) the control bones are on top of them nearly exactly and will make them hard to click. So there is a little bit of "trust me they're there". Or just use the search bar in the scene viewer and type a bone name in question, you should see it pop up.

Are you getting any sort of errors at all when you hit the "prepare for Godot" button? if not, then it's likely everything is working correctly.
