There are two main goals for Alpha releases:
For a complete list of known backward compatibility issues for version 4.3, please see Potential backward compatibility issues in Joomla 4on the documentation site.
This alpha version of Joomla 4.3 is not suitable for production sites. It is for testing only.
To always use the latest build of Joomla 4, we invite you to use the nightly build packages (updated every night).
To make it easier for newcomers, you can launch a free Joomla 4 website for testing at launch.joomla.org.
Joomla! 4.3 (general availability) is due to be released on or about 18th April 2023. The planned milestones are:
Where new features are added and many changes are made.
In the Beta stage, we are making a freeze on what features can be added, but minor changes to what is already in can be made.
When in the release candidate phase no more can be added or changed, we are testing and bug fixing making the product stable for launch day.
This whole process relies on people coming forward to help make it happen.
Please note that dates may be subject to change depending on the availability of volunteers and circumstances beyond our control.
And many more!
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 4.3. We expect to commit other features for the coming alpha releases.
Currently, we’re at the start of the journey of Joomla! 4.3. There are several projects which, with your help, could become part of Joomla! 4.3, if they are release-ready by Joomla 4.3 Beta:
To learn more about our development strategy, please read this article.
To help ensure the 4.3 release and our major features are “production-ready”, we need your help testing releases and reporting any bugs you may find at issues.joomla.org.
Most of all, we encourage extension developers to roll up their sleeves, seek out bugs and test their extensions with Joomla 4.3 and communicate their experience.
There are some tutorials to help you with 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 in https://docs.joomla.org/Category:Joomla!_4.x
We encourage developers to help write the documentation about Joomla 4 on docs.joomla.org 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: https://docs.joomla.org/JDOC:Joomla_4_Tutorials_Project
Most of the feature documentation will be needed once we have reached Beta (feature freeze).
Joomla 4.x is Joomla’s latest major version.
Joomla 3.10 was released alongside Joomla 4 as the last minor release of Joomla 3 (see this article).
Joomla 3.10 will continue to be supported until August 2023 although as its now over 15 months since the release of Joomla 3.10 and 4.0 Joomla 3 will only get security releases.
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.
If you are an extension developer, please make sure you subscribe to the general developer mailing list, where you can discuss extension development. News that may affect custom development will also be posted there from time to time.
When you subscribe to the blog, we will send you an e-mail when there are new updates on the site so you wouldn't miss them.
