Difference between Mambo The core development team of the Mambo project resigned from Miro Corporation, Australia in August 2005 and came up with a similar product Joomla! in September,2005. Joomla! made its foray into this area with its first version Joomla! 1.0. It was a refined form of Mambo version 22.214.171.124 with certain additions like bug fixes and security patches. Joomla! 1.5, the latest version of Joomla! provides language internationalization facility and uses the ‘ini’ format while Mambo 4.6 uses ‘gettext’ format for translation files. Add-ons, components, templates, modules, mambots etc. for Mambo 4.5.2 will also operate in Joomla! 1.0. It may also run on Joomla! 1.5. However add-ons for Mambo 4.6 version may not work for Joomla! 1.5 and vice versa. Some other additional features of Joomla! 1.5 include authentication models – LDAP, Gmail, etc., XML-RPC client-server support and also support of UTF-8 character set.
