Joomla team is working hard to release its Joomla 4 and it is expected that they will release the stable version at the end of 2018 or at the beginning of 2019.
Before a few days back, Joomla Project has released another alpha version Joomla 4.0 Alpha 4. You can download the latest alpha version directly from the GitHub.
There is one main goal for this Alpha release: providing third-party developers with the basis to test their extensions and reporting any issues well before the final release. This release includes most of the Joomla Core library changes that will be included with version 4.0.0. Some of these changes will require small changes to extensions.
So if you are new to Joomla 4, here is a guide to install Joomla 4 on your local server.
