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.
There are two ways to test the WordPress 5.1 beta: try the WordPress Beta Tester plugin (you’ll want to select the “bleeding edge nightlies” option), or you can download the beta here (zip).
WordPress 5.1 is slated for release on February 21, and we need your help to get there!
