Raccoon v3.7 is a maintenance release and available from it's project page.

Bugfixes:

Google changed their account creation process to no longer implicitly accept the Play TOS upon signup, resulting in Raccoon being unable to log in recently created accounts.

NOTE: this bugfix only assigns accounts to Play. But you still have to accept the TOS manually by either creating your new accounts via the Play website or at least logging in from there once.
