Hi I’m a bit late to the discussion but today I was looking for this answer and didn’t get far, so I modified the code and now versions in blender works well 
I didn’t find an up to date Deadline Repository but feel free to download the files from mine and just follow the instructions, it’s basically copy/paste.
Hope it helps.
