On 17 October 2023 Joomla 5.0 came out, together with Joomla 4.4 – two years after Joomla 4, as the new rhythm intended. From the outside Joomla 5 looks almost like Joomla 4; according to the Joomla 5.0 announcement, the work is under the hood. For this review we installed Joomla 5.0.3 of 20 February 2024, the last version of the 5.0 line, with the blog sample data and photographed it – in dark mode too.
| Released | 17 October 2023 (Joomla 5.0.0, together with Joomla 4.4) |
|---|---|
| Last version of 5.0 | 5.0.3 of 20 February 2024 (4 versions) |
| Joomla 5 in total | 32 versions up to 5.4.10 of 13 October 2026 |
| Support | bug fixes until 13 October 2026, security updates until 12 October 2027 – more in the post End of Life: Joomla 5.x |
| Requirements according to the announcement | PHP from 8.1, MySQL from 8.0.13, MariaDB from 10.4 or PostgreSQL from 12 |
| Templates | Cassiopeia (website), Atum (backend) |
| Technology | Bootstrap 5.3.2, Font Awesome 6.4, TinyMCE 6.7, CodeMirror 6 |
| Included in the installation | 241 extensions, 148 of them plugins; 11 guided tours |
An upgrade, not a migration
The most important sentence of the announcement concerns existing websites: the move from Joomla 4.4 to 5 is an upgrade, not a migration. Extensions that no longer use outdated code keep working; for most others there is the "Behaviour – Backward Compatibility" plugin. Joomla 4.4 itself brought no new features but prepared this path.
What's new in Joomla 5
New in Joomla 5, according to the announcement, are among other things a refined dark mode in the backend, structured data following Schema.org, AVIF images in the Media Manager, menus you can sort freely, TinyMCE 6.7 with image alignment, CodeMirror 6 and Font Awesome 6.4. Plus a lot of clean-up in the code and higher minimum requirements: PHP 8.1 and MySQL 8.0.13.
The installation
The installer is the same as in Joomla 4, including the ownership check for databases on other servers.
The website: Cassiopeia
The backend
The end-of-support notice comes from Joomla itself: the plugin "Quick Icon – Joomla 5 End Of Support Notification" has the date built in, in 5.0.3 it is 19 October 2027. Joomla's current roadmap gives 12 October 2027 for security updates. "Take a Tour" at the top of the bar is new as well.
New in the backend
Extensions and system
2023 and today
Between 5.0 and 6.2 the picture stays almost the same – which also shows that the way to Joomla 6 is not a fresh start.

Is your website on Joomla 5?
Since 13 October 2026 Joomla 5 only gets security updates, until 12 October 2027. The way to Joomla 6 leads via 5.4 and is an upgrade – we plan it with you and check your extensions first.
See Joomla update and migrationHow we did it: Joomla 5.0.3 in the original package from downloads.joomla.org, locally in Docker with PHP 8.2 and MySQL 8.0, reachable only on our own machine, files unchanged, with the blog sample data. The red warning that PHP 8.2 is outdated only appears because this old Joomla version expected PHP 8.2 to end on 8 December 2025; PHP later moved that to the end of 2026 – we closed it with its own button before taking the picture. Atum shows the dark mode when the system is set to dark. Joomla 6.2 fresh with sample data.
