The new version uses the new Woopra API and adds avatar support, with integration with systems like Community Builder, JFusion, Kunena (untested), JomSocial (untested), and some Gravatar default generated avatars like Monsterid, Identicon and Wavatar. There has also been a few more options added.
Publish the module in the debug or footer module position and enter your Woopra ID in the parameters. You also have the option to track user information with this module. This way, if visitors are logged in, their username, email and avatar will show up in the Woopra statistics! You also have the ability to disallow tracking of logged in admins, as well as a few other options.
