This release added support for more languages and more help items in the UI, including help on the popup dialogs. In the dependencies tree you must now use Shift+Click to select a file and all of its dependencies. Clicking alone will select the file only, not its dependencies. The REST API specs docs were updated to match the 2.1 implementation. DITA documents are now properly indexed and thus searchable. There were many UI enhancements and bugfixes.
