Mambo (formerly named Mambo Open Source or MOS) is a free software/open source content management system (CMS) for creating and managing websites through a simple web interface. It has attracted many users due to its ease of use.
Mambo includes advanced features such as page caching to improve performance on busy sites, advanced templating techniques, and a fairly robust API. It can provide RSS feeds and automate many tasks, including web indexing of static pages.
Advanced interface features include printable versions of pages, news flashes, blogs, forums, polls, calendars, website searching, language internationalization, and many others.
Mambo is released under the terms of the GNU General Public License (GPL)Version 2. It is written with the PHP programming language and uses the MySQL database.
As of 24 April 2007, the minimum requirements for Mambo consist of:
- Apache (version 1.3.19 or above) or Windows IIS
- MySQL (version 4.x or above)
- PHP (version 4.3.x or above with extensions: mysql, xml, zlib, ftp)
Mambo is thoroughly tested on Linux, FreeBSD, Mac OS X and Windows NT/2000/XP/Vista. Linux or one of the BSD's are recommended, but anything else that can run the three pieces of software listed above should work. Additionally, Mambo displays properly in most major browsers: Internet Explorer (version 5.5+), Netscape, Opera and Mozilla/Firefox.
PHP must have been compiled with support for MySQL and Zlib in order to successfully run Mambo. Mambo works on Microsoft IIS, but Apache is recommended for running Mambo on Windows.
The rights to the Mambo CMS codebase, name and copyrights, are protected by the Mambo Foundation, a non-profit corporation formed to support and promote the Mambo Open Source project.
The Mambo Foundation is a non-profit entity established under the laws of Australia. The Foundation is based on Eclipse and GNOME and is controlled by the members of the Foundation via an elected Board of Directors. The Mambo Foundation's brief is to foster the development of the Mambo system and to shelter the project from threats and misuse. The Foundation was formed in August 2005. The Mambo Foundation also has forums addressing the latest issues within Mambo, including the deployment of Mambo 5.
Timeline of Mambo History
- 2000: Miro Construct Pty Ltd, registered in March 2000 in Melbourne, and headed up by CEO Peter Lamont, a former advertising executive, starts development of Mambo, a closed-source, proprietary content management system.
- 2001: The company adopted a dual licensing policy, releasing Mambo Site Server under the GPL on Sourceforge in April 2001.
- May 2001: The mamboserver.com domain name is registered.
- From this time until the middle of 2002, Miro was the only developer of Mambo, contributing bug-fixes and security patches but not really extending the code or adding to the feature sets.
- 2002: Miro releases the commercial CMS called Mambo 2002.
- With version 3.0.x, the open source Mambo Site Server becomes "Mambo Open Source" (commonly referred to as "MOS").
- Robert Castley becomes Project Director of Mambo Open Source. 
- By the end of 2002, Robert Castley had pulled together a volunteer team of developers.
- Mambo Open Source 4.0 is released.
- 2003: Early in 2003, Miro hands off the responsibility of the code fully to the Open Source project Development Team.
- Miro concentrates on its commercial products and Mambo Open Source builds momentum under the leadership of Robert Castley.
- Miro released Mambo CMS, a commercial version of Mambo Open Source. Miro claims that Mambo CMS does not contain any source added to Mambo after it was made open source. 
- Miro Construct Pty Ltd goes into voluntary liquidation in February 2003 and in August, Miro International Pty Ltd is formed. Source code for Mambo Open Source shows copyright 2000 - 2003 Miro Construct Pty Ltd.
- Mambo Open Source 4.5 released in December 2003. By this time, almost all of the original Miro code had disappeared during refactoring.
- 2004: mamboforge.net starts in March, 2004.
- Linux Format awards Mambo “Best Free Software Project” of the Year.
- Linux User and Developer names it “Best Linux or Open Source Software”.
- In late 2004, Mambo was targeted by legal threats concerning the intellectual property rights to certain pieces of code contained in the core. The problem was severe and cost money, man hours, and eventually the loss of some key community leaders. Miro came to the aid of Mambo, offering legal and corporate resources to protect the development team and preserve the program.

- Versions 4.5.2 and later, 220.127.116.11 are released.
- March 2005: The name "Mambo Open Source" (which was commonly referred to as MOS) was changed to just "Mambo", causing concern in the community over apparent confusion this would cause between the open source, community-developed CMS and Miro's commercial offering, "Mambo CMS".

Domain Names, hosting etc. " and goes on to say that with him, the original founder of Mambo Open Source, and Andrew Eddie both being on the Board of the Mambo Foundation, Mambo would continue as a successful, open source project. He concluded his statement with,"So there you have it: two very key people in the overall success of Mambo are at the helm. Trust me, Mambo is in very, very safe hands!"
- A few days later, the entire team of core programmers publicly announced they had abandoned Mambo and shortly after this, Robert Castley steps down from the Board of Regents. 
- The former core development team members regroup under the name "Open Source Matters" and the open source community at mamboserver.com fractures over allegations that the Mambo Foundation was formed without community input and with insufficient developer control. People express suspicion over the level of involvement by Miro International. By the end of August, the new project is named Joomla! and most of the former Mambo community has relocated to Open Source Matters. By the end of September, Open Source Matters Inc is a duly constituted non-profit corporation registered in New York.
