This software is still in development, so we don’t recommend you run it on a production site. Consider setting up a test site to play with the new version.
You can test the WordPress 5.4 beta in two ways:
Try the WordPress Beta Tester plugin (choose “bleeding edge nightlies” or “Beta/RC – Bleeding edge” option in version 2.2.0 or later of the plugin) * you must already have updated to your site to “bleeding edge nightlies” for the “Beta/RC – Bleeding edge” option to be availableOr download the beta here (zip). WordPress 5.4 is slated for release on March 31st, 2020, and we need your help to get there.
Thanks to the testing and feedback from everyone who tested beta 2 (and beta 1) over 24 tickets have been closed in the past week.
