WordPress 5.9 Beta 3

WordPress 5.9 Beta 3 is now available for testing!

This software version is still under development. Please do not run this software on a production site; install it on a test site, where you can try out the newest features and get a feel for how they will work on your site.

You can test the WordPress 5.9 Beta 3 in three ways:

Option 1: Install and activate the WordPress Beta Tester plugin (select the “Bleeding edge” channel and “Beta/RC Only” stream).

Option 2: Direct download the beta version.

Option 3: If you use WP-CLI to upgrade from Beta 1 or Beta 2 to Beta 3 on a case-insensitive filesystem, please use the following command sequence:

Command One:

wp core update --version=5.9-beta2

Command Two:

wp core update --version=5.9-beta3 --force

The current target for the final release of 5.9 is January 25, 2022, which gets closer every minute. Your help testing this beta is vital: the more testing that happens, the more stable the release, and the better the experience for users and developers—and the entire WordPress community.
