Joomla 4.2.1 Alpha3- Last main additions inside

The Joomla Project is pleased to announce the availability of the third Joomla 4.2 Alpha for testing.

What is this release for?

There are two main goals for Alpha releases:

  • Providing developers with the basis to test their extensions and reporting any issues well before the final release

  • Allowing users to discover the new features introduced to Joomla 4.2.

We are firmly committed to making the next generation of Joomla the best. So far, these are the features that have been committed to version 4.2.

What are the plans for Joomla 4.2?

Currently, we’re at the mid way of the journey of Joomla! 4.2. There are several projects which, with your help, could become part of Joomla! 4.2, if they are release-ready by 1st June 2022:

Shortcut keys: Make it easier to perform tasks in Joomla! Using keyboard shortcuts

Cookie Manager: Manage your site cookies in a centralized manner

We are now feature-ready for Joomla! 4.2 and can now concentrate on stabilizing Joomla! 4.2 over the coming weeks. To make this happen we need a few last tests for the listed PRs.

To learn more about our development strategy, please read this article.

How can you help Joomla 4.2 to develop?

To help ensure the 4.2 release and our major features are “production-ready”, we need your help testing releases and reporting any bugs you may find at

Most of all, we encourage extension developers to roll up their sleeves, seek out bugs and test their extensions with Joomla 4.2 and communicate their experience.

We would like to remind our users that Joomla 3.10 intends to be the last release of the Joomla 3.x series and will primarily be a release containing backports of API changes from the Joomla 4.x development branch to help ease the transition to the next major release for the community.

We’re focusing on Joomla 4 to make it the best. Therefore, we do not plan to release any more 3.x minor versions - unless it proves to be really essential. All feature proposals should be directed toward the 4.2 release.

We are looking for users to help test a number of improvements for Smart Search, please take some time to test these great changes to the Smart Search so we can include them in the 4.2 release.

Where can I find documentation about Joomla 4?

We have started to provide some tutorials to help you with Joomla 4. We’ll be writing more tutorials to help you understand the significant changes of Joomla 4. You can find the existing ones, like creating a Plugin or a Module for Joomla 4, namespaces conventions, prepared statements, using the new web asset classes and many more here.

We encourage developers to help write the documentation about Joomla 4 on to help and guide users and other extension developers.

A JDocs page will help developers to see the existing documentation, and the documentation still needed.

We invite you to check it regularly, update it and provide the missing content:

Most of the feature documentation will be needed once we have reached Beta (feature freeze).

Should I plan to upgrade to Joomla 4.x?

Joomla 4.x is Joomla’s latest major version.

Joomla 3.10 is released alongside Joomla 4 as the last minor release of Joomla 3 (see this article).

Joomla 3.10 will continue to be supported for two years from its release, giving you plenty of time to plan your migration to Joomla 4 and update your extensions (if required) to become Joomla 4 compatible versions.

As it is now more than six months since the release of J4.0 you should be planning or in the process of migrating to the latest version of Joomla.

We provide resources to help with the migration on the documentation site.
