We've made two changes to our repository configuration as brought up in the forum (http://community.jboss.org/message/545189).  The first is that the proxy repositories have been added to the public group.  This means that the public configuration can be used for both anonymous and developer builds.  This should not have an impact on existing build configurations and it should allow the recommended build configuration to be simplified.

The other configuration change that took place over the weekend is that the server has been configured to allow standard http requests for the public repository group (http://repository.jboss.org/nexus/content/groups/public/).  Other parts of the repository (including anything that requires a login) will still require https.  No formal performance testing has been done so far, but downloads seem to be significantly faster using standard http.

The wiki documentation related to the recommended Maven settings will be updated this week to reflect these changes.
