WordPress 5.9 RC3

The third Release Candidate (RC3) for WordPress 5.9 is here!

Thank you to everyone who has contributed thus far toward testing and filing bugs to help make WordPress 5.9 a great release. WordPress 5.9 is slated to land in just one week—on January 25, 2022. You still have time to help! Since RC2 arrived last week, testers have found and fixed two bugs, 14 fixes from Gutenberg. There has been one additional Gutenberg fix today.

Testing the release

You can test the WordPress 5.9 release candidate 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: Download the beta version here (zip).

Option 3: When using WP-CLI to upgrade from Beta 1, 2, 3, 4, RC1, or RC2 on a case-insensitive filesystem, please use the following command sequence:

Command One:

wp core update --version=5.9-RC3

Command Two:

wp core update --version=5.9-RC3 --force

Your help to test the third Release Candidate is vital: the more testing that happens, the more stable the release, and the better the experience for users, developers, and the WordPress community.

Thank you to all contributors who tested the RC2 release and gave feedback. Testing for bugs is a critical part of polishing every release and is a great way to contribute to WordPress.
