Nope, it updating using the 'source' method. Someone else had a problem updating so I suspect there was a bad update somewhere down the line (this is on CouchPotato's side and I recall this happening a few times in the past). I posted a manual fix, you should try this.
This doesn't seems to affect new installbecause CouchPotato because CouchPotato grabs the latest versions when you go through initial install.
That's strange because this was on a fresh install last night :S
I'll try again tonight in a separate jail to do some testing. I've noticed updating issues on CouchPotato's side in the past as well.
Worst case I can always update the files manually. It's just a change to the API functions :)
Thank you as always!
