Drupal 8 is an open-source content management system (CMS) that allows users to create and manage websites easily. Released in November 2015, it introduced significant improvements over its predecessor, Drupal 7, including a more user-friendly interface and enhanced mobile responsiveness. One of the key features of Drupal 8 is its use of the Symfony framework, which helps developers build complex applications more efficiently. It also supports modern web standards, such as HTML5 and RESTful web services, making it a versatile choice for various types of websites, from blogs to large enterprise platforms.
