After an unsettling loss of the Mambo developers that migrated over to the the Joomla project...dedicated Mambo users can breath a little easier. The newest verison of Mambo has the usual improvements and new features, but we think new users will like these two new features the most:

• ability to view, backup, restore, and query database from within Mambo;
• Universal Installer - one installer handles installation of all extensions
