There will be a minor WPS 3.X release soon. This will not contain a WPS 2.0 interface. We are planning a new major WPS 2.0 compliant release within the first half of this year. This will be a new project based on iceland. There exists a development branch based on the current WPS implementation also exposing a WPS 2.0 interface: https://github.com/52North/WPS/tree/wps-4.0 This one has also a new configuration mechanism. We've been working on this branch for a while but we decided to restart from scratch to have a nice and clean implementation at the end.
