WordPress 5.5 Beta 4 is now available!

This software is still in development, so it’s not recommended to run this version on a production site. Consider setting up a test site to play with the new version.

You can test WordPress 5.5 Beta 4 in two ways:

• Try the WordPress Beta Tester plugin (choose the “bleeding edge nightlies” option)
• Or download the beta here (zip).

WordPress 5.5 is slated for release on August 11th, 2020, and we need your help to get there!

Thank you to all of the contributors who tested the beta 3 development release and gave feedback. Testing for bugs is a critical part of polishing every release and a great way to contribute to WordPress.

Some highlights

Since beta 3, 43 bugs have been fixed. Here are a few changes in beta 4:

• Add "loading" as an allowed kses image attribute (see #50731).
• Add filter for the plugin/theme auto-update message in the Info tab of Site health (see #50663).
• $_SERVER['SERVER_NAME'] not a reliable when generating email host names (see #25239)
• Several backported fixes from Gutenberg are included in WordPress 5.5 Beta 4 (See PR #24218)

Developer notes

WordPress 5.5 has lots of refinements to polish the developer experience. To keep up, subscribe to the Make WordPress Core blog and pay special attention to the developers’ notes for updates on those and other changes that could affect your products.
