[Serusers] ser stable to unstable ?

Hello, I have a working config with ser cvs stable and I want to test new modules from cvs unstable. If I try to use the same config file with the cvs unstable I have errors with auth_db and db_url . What has changed between ser cvs stable and ser cvs unstable ?
