- Bootstrap 5.3
- Codemirror 6
- B/C plugin for deprecations - #40664
- Joomla! Cookie Manager - Project Repository

How can you help Joomla 5.0 to develop?
To help ensure the 5.0 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 5.0 and communicate their experience.
Where can I find documentation about Joomla 5?
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!_5.x
We encourage developers to help write the documentation about Joomla 5 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).
