Joomla users and extension developers are asked to download and install the packages in order to provide quality assurance for the forthcoming 4.0 and 3.10 releases.
Joomla! 4 is the latest major release of Joomla! CMS. Please note that going from 3.9 to 4.0 is a migration. You would need to upgrade your J3.9 to J3.10, which will be available the day J4.0 is stable. J3.10 has a compatibility checker to help guide you through the migration to J4.0. Please do not upgrade any of your production sites to the release candidate version!
What is this release for?
Joomla 4.0 RC5 is aimed at extension and template developers. To encourage them to work with this release in order to prepare extensions for the stable release of Joomla! CMS 4.0. Users are encouraged to test the package for issues and to report issues in the Joomla! CMS Issue Tracker. Test sites based on this release candidate can be taken through to stable but never use this version on a production site. There will be an upgrade path between release candidates and the final release candidate to the stable of Joomla 4.0 should you wish to try a new site build.

Joomla 3.10 helps with the transition to Joomla 4
Along with Joomla 4 RC5, we are releasing the first release candidate version of Joomla 3.10.
Joomla 3.10 is the bridge between the 2 major series. Joomla 3.10 stable will primarily be a release containing backports of API changes from the Joomla 4.0 development branch to help ease the transition to the next major release for the community. Joomla 3.10 will be supported for 2 years after it has been finally released.
Once your website is updated to 3.10, the pre-update checker will allow you to check the compatibility with the Joomla 4.0 minimum requirements in terms of the current hosting environment and, more importantly, your installed extensions. This will help you migrate to Joomla 4.0 smoothly.
Can I update my website from 3.9.x to Joomla 4 RC5?
The simple answer here is yes. Not on a production site of course, but if you want to test the update to Joomla 4, now you can.
In order to upgrade from 3.9.x to Joomla 4, you have to go via the latest 3.10 release. There is no direct upgrade path between 3.9 and 4.x planned nor supported. All upgrades go via 3.10.
For the upgrade please follow these steps:
- Go to the Joomla Update Component Options and switch the Update Channel to “Testing” and the Minimum Stability option to “Alpha”.
- Update to the latest 3.10 release candidate using the Joomla Update Component.
- Switch the Update Channel to “Custom URL” and set the Custom URL to “https://update.joomla.org/core/test/310to4_list.xml”
- Now you get, update to the latest 4.0 Release Candidate.
- Please carefully check the results from the pre-update checker in terms of your environment and your installed extensions before upgrading.
- After the upgrade please switch back to the “Testing” Update Channel with the “Release Candidate” minimum stability to get future updates between Joomla 4 RCs.
If you need more details on the upgrade process you can find them in the documentation.

How can you help Joomla! development?
There are a variety of ways in which you can get actively involved with Joomla. It doesn't matter if you are a coder, an integrator, or a user of Joomla. You can contact any of our volunteer engagement team to get more information, or if you are ready you can jump right into the Joomla! Bug Squad.
The Joomla! Bug Squad is one of the most active teams in the CMS development process and is always looking for people (not just developers) that can help with sorting bug reports, coding patches and testing solutions. A great way for increasing your working knowledge of the Joomla! code base, and also a great way to meet new people from all around the world.
If you are interested, please read about us on the Joomla! Wiki and, if you wish to join, email Jacob Waisner,
You can also help Joomla! development by thanking those involved in the many areas of the process. The Project also wants to thank all the contributors who have taken the time to prepare and submit work to be included in the Joomla! CMS and Framework.
A Huge Thank You to Our Volunteers!
This Release Candidate release is the result of thousands of hours of work by dozens of volunteers.
The changes from RC4 to RC5 alone contain
- Rename the CSS variables for the Atum + Cassiopeia (they no longer have the template in the name to allow easier reuse in child templates)
- Many RTL Fixes
- Update of alert custom element
- Removed `acknowledge` attribute
- Removed `href` attribute
- Added `close-text` attribute. This should be used to load the close button with multilingual text when the dismiss attribute is used
- Update of tab custom element
- The <section> attribute inside the <joomla-tab> element has been changed to <joomla-tab-element>
- A breakpoint attribute has been added to control at what screen size to fallback from tabs to accordion.
A big thank you goes out to everyone that contributed to the 4.0 release! Right now we're over 46,093 commits with many different people contributing to those commits (not including testers and other non-coding activities).
