The wiki software that is used for geoserver.org (Confluence) has been upgraded from 2.5.7 to the latest version (2.8.1). So far, some things look a little different, but mostly are unchanged. If you notice anything troubling about the site, please let me know. This is part of slightly broader strategy of making the wiki easier to use.
Massive amounts of thanks go to Arne Kepp, who shadowed me throughout the upgrade process.
Thanks,
Mike Pumphrey
