There are no current plans to update Hawthorn.
On the server side, Hawthorn runs as an independent server that can be integrated with your website via libraries for JSP and PHP developers. (Support in other languages is also possible.)
Hawthorn includes built-in support ('connectors') for some systems, initially only the Moodle open-source virtual learning environment. Hawthorn is open source (GPL3) and we welcome contribution of additional connectors.
Please see the Hawthorn manual for more details.
