Mambo Open Source 4.5 is almost a complete re-write of the code base. Many new features and enhancements have made it into the code. Also a number of security issues have also been addressed.

Here are the minimum requirements for MOS 4.5

• PHP 4.1.2 or above - http://www.php.net
• MySQL 3.23.x or above - http://www.mysql.com
• Apache 1.13.19 or above - http://www.apache.org

You must ensure that you have MySQL and XML support built into your PHP.

In order to benefit from Mambo's now famous administrator interface this is best achieved on the Windows platform using Internet Explorer. We have implemented htmlarea (www.interactivetools.com) for the WYSIWYG editor and this ONLY works under Windows and Internet Explorer.

Extensive testing has also been completed using Mozilla 1.4 but the WYSIWYG editor is not available in this browser.

We anticipate that the administrator interface will not function correctly in other browsers. This is due to the fact that in order to bring you the easiest to use open source CMS we have had to introduce technology that is not always cross browser compatible, as Internet Explorer covers the majority and Mozilla 1.4 is available for many other platforms other than Windows.
