Review: Joomla 3.10

Joomla 3.10 came out the same day as Joomla 4.0 as "the bridge": it contains interfaces from Joomla 4 and checks before the move whether server and extensions are ready. For this review we installed Joomla 3.10.12 of 11 July 2023, the last version of this line, and photographed it.

Still running a website on Joomla 3?

It gets no security updates any more. We bring it to Joomla 6 – we name the effort after an inventory.

See Joomla update and migration

How we did it: Joomla 3.10.12 in the original package from downloads.joomla.org, locally in Docker with PHP 7.4 and MySQL 5.7, reachable only on our own machine, files unchanged, with the "Learn Joomla" sample data. PHP error display is switched off so that notices about outdated functions do not cover the pictures. The red warning that our PHP is outdated only appears because we run the old version today – we closed it with its own button before taking the picture.
