The Joomla open source CMS, which is offered under the General Public License (GPL) version 2.0, is a continuation of the work of the development team that unanimously resigned from the Mambo project in August 2005 (see “fork“). Joomla version 1.0 is derived from Mambo 126.96.36.199 but includes many additional bug fixes and security patches.
The Joomla Web CMS is considered to be a popular choice for many types of websites, including corporate sites, news or blogs, government applications, small business sites and sites where secure logins are required. The ecosystem of Joomla developers and users provide products and services to the Joomla community which has more than one-half million members and more than 20,000 developers.
Organizational, legal and financial support for the Joomla! open-source project is provided by the non-profit organization, Open Source Matters (OSM). OSM is responsible for all project activities that are not the responsibility of the production working group or the community working group, such as operations management, events, the shop, marketing and public relations.
