This meeting focuses on core framework development, rather than on usage of the framework. In this context, it will provide an opportunity for updates on features currently under scoping and/or development, as well as current technical issues and planning for future features.
This meeting has been supplanted by the Users Group Meeting and the Core Developers Meeting.
