Upgrade to Joomla 6

The main goal of Joomla 5.4.x releases is to prepare websites for a smooth upgrade from Joomla 5.x to Joomla 6.x. New websites we build directly on Joomla 6.x. Existing websites are upgraded when the server setup (PHP and database versions) and installed extensions fully support Joomla 6.
