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 RC4 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.
Spotlight on Joomla4Speed
When in competition with other sites and your visitors' attention it's important to make sure your site has the best performance possible. You put all the hard effort into excellent articles, great design so you need a blisteringly fast CMS to deliver that crafted content. With Joomla 4 and a good hosting provider you get lightning speed as measured by the main independent arbitrator in such matters: Google Lighthouse
To test the speed and performance of Joomla 4 we used our global platinum sponsors, Scalahostings cloud VPS solutions and Rochen hosting. With default install of both CMS and hosting package we scored an impressive 100% for Performance. You cannot get better than that and all without customisation or fine tuning.
So why not test your own site with Google lighthouse? If your results are less than in the green with scores below that 100% then it's time to migrate to Joomla 4 and see the visitor and page ranking boost your site deserves. Joomla4Speed
