What is this release for?
There are two main goals for Beta releases:

We are firmly committed to making the next generation of Joomla the best. So far, these features have been committed to version 4.2.
What are the plans for Joomla 4.2?
We are now feature-ready for Joomla! 4.2 and can now concentrate on stabilizing Joomla! 4.2 over the coming weeks.
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 issues.joomla.org.
Most of all, we encourage extension developers to roll up their sleeves, seek out bugs and test their extensions with Joomla 4.2 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 the outstanding changes for the 4.2 release. You can find the list of changes here: https://github.com/joomla/joomla-cms/pulls?q=is%3Apr+is%3Aopen+label%3APR-4.2-dev+
There is a document to help you find out and learn how to test these changes, including some videos.

Come and join us in building great Joomla releases.
Multi-factor authentication
Up until now, Joomla only offered Two Factor Authentication, with multi-factor authentication, we are taking authentication one step further by allowing you to choose different kinds of authentication mechanisms to secure your site. You can choose to use a Yubi-key, Web Authentication, a verification code, or code by email.
The way multi-factor authentication works is that you first log in with your username and password, and after that, you are presented with another screen to enter your second authentication method.
This means that you will no longer be able to enter your two-factor authentication code on the same page as the login page.
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 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).
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 almost 10 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.
