Drupal is a popular open-source content management system written in PHP. Having been created in the early 2000s by a Belgian student, it now powers some of the most prominent websites on the web (WhiteHouse.gov, Weather.com, etc.). It is often regarded as a competitor of CMSs such as WordPress and Joomla.
One of the most important components of the Drupal project is its community of supporters (contributors, developers, evangelists, business owners, etc.). Prominent within this community stands the Drupal Association, responsible for "fostering and supporting the Drupal software project, the community and its growth".
A giant leap from its predecessor, the 8th major release of the Drupal project has just hit the shelves. It brought about a serious modernisation of its code, practices and mentality. Many regard this shift as a real move away from the traditional notion of a CMS to more of a Content Management Framework (CMF) that provides a great platform for building complex applications
