Joomla 4.1 Alpha 3 - Proposed new features

The Joomla Project is pleased to announce the availability of the third Joomla 4.1 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 4.1.

For a complete list of known backward compatibility issues for version 4.1, please see Potential backward compatibility issues in Joomla 4 on the documentation site.

What is this release NOT for?

This alpha version of Joomla 4.1 is not suitable for production sites. It is for testing only.

What’s new in Joomla 4.1?

We are firmly committed to making the next generation of Joomla the best. So far, these are the first features that have been committed to version 4.1. We expect to commit other features for the coming alpha3 releases.

What are the plans for Joomla 4.1?

Currently, we’re at the start of the journey of Joomla! 4.1. There are several projects which, with your help, could become part of Joomla! 4.1, if they are release-ready by 7th December 2021:

  • Improvement of language support within articles > See here
    => Merged and available
  • Better support for code highlighting in TinyMCE editor > Test here
    => Needs the last final test to be merged
  • Enhancement of the Media Manager Web Service > Test here
    => Needs one final test to be merged
  • Task Scheduler (Web cron) for Joomla > Test here
    => Ready to be merged, but was postponed a few days because of an issue in Joomla! core
  • Accessibility Checker for authors > More information
    => Made a lot of good progress the last few weeks and should be ready for testing the next few days.
  • And many more!

We’re very close to being feature-ready for Joomla! 4.1 and can then concentrate on stabilizing Joomla! 4.1 over the coming weeks. To make this happen we need a few last tests for the listed PRs.

How can you help Joomla 4.1 development?

To help ensure the 4.1 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 4.1 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 4.1 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, giving you plenty of time to plan your migration to Joomla 4 and update your extensions (if required) to become Joomla 4 compatible versions. We will provide resources to help with the migration on the documentation site.
