Joomla 4 was designed to modernize the platform, moving away from the legacy code of Joomla 3 to offer a more secure, faster, and accessible web development experience.
By utilizing cleaner code and modern PHP versions (PHP 7.2.5+ required), Joomla 4 offers faster page load times out of the box compared to its predecessor.
One of its standout features is the new Workflow system. It allows site administrators to define custom stages for content (e.g., Draft, In Review, Published), which is essential for multi-user editorial teams.
