Invalid Sentry DSN in Python

Just recently migrated to SAAS Sentry and created a project. The page no longer lists a “Public DSN” and a “Private DSN”, just a “DSN”.
However when I use this DSN in the latest Python Raven (6.6.0) I get the error raven.exceptions.InvalidDsn: Invalid Sentry DSN: 'https://xxxx@sentry.io/xxx'

I fixed it by using the “DSN (Legacy)” at the bottom of the list. There doesn’t seem to be a newer version of raven out, so I’m not sure if 6.6.0 would be considered legacy or if I’m just doing something else wrong
