In Joomla! 1.5, you’ll notice:

  • Substantially improved usability, manageability, and scalability far beyond the original Mambo foundations

  • Expanded accessibility to support internationalisation, double-byte characters and right-to-left support for Arabic, Farsi, and Hebrew languages among others

  • Extended integration of external applications through Web services and remote authentication such as the Lightweight Directory Access Protocol (LDAP)

  • Enhanced content delivery, template and presentation capabilities to support accessibility standards and content delivery to any destination

  • A more sustainable and flexible framework for Component and Extension developers

  • Backward compatibility with previous releases of Components, Templates, Modules, and other Extensions
