Hi Ciarán,
https://docs.joomla.org/Potential_backward_compatibility_issues_in_Joomla_4
"This document tracks potential backward compatibility issues for Joomla! 4. Listed are issues which potentially break extensions.
The base of this comparison is Joomla! 3.7. Updated System Requirements
The system requirements have been updated as follows:
PHP 7
MySQL 5.5.3
PostgreSQL 9.2
SQL Server support has been dropped.
PHP MySQL Extension - Joomla no longer supports using PHP's ext/mysql driver (which was removed in PHP 7.0). Joomla will automatically try and use the mysqli extension (available since PHP 5.3) or the mysql PDO Driver (available since PHP 5.3) else it will fail to create a database connection."
My databases are "mysql". If SQL server support has been dropped, is that not the same as "mysql"? Which interpret as being that my database will not connect if I do all of the upgrades required for Joomla 4.0?
This is where my confusion comes from. I would really appreciate some help understanding all this. Your help has always been phenomenal in this forum.
Thank you - -from Canada!
