There is a new version of the IDEA AddOn with some minor upgrade on the helpers for data modeling. But there is a mayor upgrade on the HTML generator in IDEA for generating static HTML pages on a package in a repository including the subpackages. Most important changes in the HTML generator are:

• Improvement of the startpage with a more attractive layout of the navigation to packages, diagrams and elements
• Overview of on which diagrams an element is visible from the element details page

You can download the new version from IDEA tool page
