Wing Next is the current pre-release version of the Wing programming language. It is not supposed to be used by regular users, and therefore will not receive any form of support besides bug reporting.
Once the required changes in the Wing language have been completed, the current Next version becomes the next Beta version, where bugs will need to be caught. Once testing is complete, the Beta version becomes the next public version.
Wing Next does not follow the same lifecycle as stable releases since it is an ever evolving version of the language.
