It is now possible to disable the WebHelp zoom functionality for particular images. You can flag the images that should not have zoom functionality by using the no-zoom value for the @outputclass attribute on the particular images.

You can control whether clicking the URL for a custom WebHelp logo will open it in the same tab or in a new tab. This can be configured using the new webhelp.logo.image.target.url.new.tab parameter. By default, the link is opened in the same tab as the WebHelp output.

It is possible to display certain elements as tabs by using the outputclass="wh-tabbed" attribute. This works for lists (<ol>, <ul>), definition lists (<dl>), and choice table (<choicetable>) elements.
