This has been the case since 1.7.0 was released…
See
https://docs.pylonsproject.org/projects/webob/en/stable/whatsnew-1.7.html#backwards-incompatibility
specifically:
- Response.set_cookie no longer accepts a key argument. This was deprecated in WebOb 1.5 and as mentioned in the deprecation, is being removed in 1.7
Recently some changes were made to remove any last references to `key`, so that things would error if you did try to use it, but those are on master only and have not been back ported to 1.8-branch (yet, I may still do that. I forgot to do it this go-around).
