The project is hosted on GitHub: https://github.com/joomlaworks/joomla-3.x
First release of Joomla 3.x UTD, version 3.11, was uploaded on Monday, Apr 20th, 2026.
Joomla 3.x UTD is currently compatible with PHP 7.1 and up to 8.5 and is tested with latest versions of MySQL (8.0 & 8.4 LTS) & MariaDB (10, 11 and 12) at the time of writing. As we roll newer releases, we will test against more recent versions of Postgres as well.
Please note that the point of this project is to ensure Joomla 3.x works with new PHP & MySQL/MariaDB versions and remains secure, for those who still use it.
As such, any contributions should focus towards that goal, as well as any bugs they may have existed in Joomla 3.x and which were never resolved due to the Joomla core team's change of focus to newer releases.
This distribution is obviously a community project, not an official Joomla project.
As always, thanks goes out to all the people who built and contributed to Joomla 3.x until its EOL date.
Update on July 19th, 2026:
We're continuing to roll out updates. The last one, v3.15, includes many security issues discovered in Joomla 5/6, backported to Joomla 3.x UTD, along with further improvements and bug fixes in Joomla 3.x.
