+As OGS-6 is a reimplementation of OGS-5 with new concepts and methodologies there will probably never be complete feature parity. We provide binaries of OpenGeoSys-5 ready for you to use. Support is limited but you may ask questions or report bugs via the [ogs-users](https://groups.google.com/forum/#!forum/ogs-users) mailing list.
