Some time ago we published news related WCS4-beta. For now our beta passed a lot of tests and it is going to RC status – release candidate. Almost all test cases are passed well. A couple of errors remain. We are not waiting any serious updates and changes in the API. Therefore you can begin with WCS4 right now. For a while we continue to work with the server to present the release very soon.
Happy New Year 2015!
