Joomla 4 will move towards using prepared statements for all database queries. PHP 5.3 introduced the concept of prepared statements. Joomla 4 will start taking advantage of them. The main advantage of prepared statements is to reduce the exposure of a code base to SQL Injection attacks by sending the query and the data separately.
Joomla 4.0 is Joomla’s new major version. Joomla 3.10 is released alongside Joomla 4 as the last minor release of Joomla 3. Joomla 3.10 will continue to be supported for 2 years giving plenty of time to webmasters to plan migration to Joomla 4 and update extensions to Joomla 4 compatible versions.
Modules are lightweight and flexible extensions that are displayed in pages at different module positions. These modules are displayed like boxes arranged around a component in top, sidebar or footer position. For example, login module or html module.
