What is the new Network Admin section?

Question

Previously, in WordPress 3.0, multisites were managed through a Super-Admin section of the administration interface. The 3.1 update seems to have moved the administration of multisites to a new "Network Admin" section, which has a similar layout to the standard WP administration panels, but only contains options related to network administration.

This section, however, seems to be pretty similar to the old Super-Admin section. Has there been any additional network management features added, or is the Network Admin section just a separation of options?

Answer 1

Basically they moved Super Admin menus and related pages out of the regular admin and into a new Network Admin screen.

and the updates are:

• Add contextual help for Network screens
• Add delete support to network themes
• Add plugin update notifications, plugin install, plugin update to the network admin screen
• Admin Bar similar to that used in wordpress.com blogs (#14772)
• Move network version of Tools->Network to the network admin
• Move theme installer to the network admin for multisite installs
• Network Admin (#14435)
• Network Wide Settings->Language Settings
• New Network Admins page for Theme enable/disable/upgrade
• Pass more information to notification filters
• Rename Update menu to Updates in network admin
• Revamp User-new.php including separate caps for adding users vs. creating users, allowing supes to add via email or username, split adding existing users and creating new users into separate forms
• Support wildcard domains in WP_PROXY_BYPASS_HOSTS and WP_ACCESSIBLE_HOSTS
• Tabbed interface for site editing
• User Admin feature creates a separate "personal" dashboard to provide a single endpoint for accessing profile information, cross-site preferences, a launching point for accessing all of a user's blogs, collation of stats across all of a user's blogs, a place for a multisite aware quick press, etc. (#14696)
