WordPress 6.0 is the latest major release of WordPress and is currently available on the Pantheon platform. This release features nearly a thousand enhancements and bug fixes.
If you’ve updated the previously released Twenty Twenty-two theme outside of Pantheon's WordPress upstream, updating to WordPress 6.0 will result in an error, due to the removal of the wp-content/themes/twentytwentytwo/assets/fonts/LICENSE.md file. To resolve this error delete this file, commit, and push your change, then reapply the update. Detailed information on applying and debugging core updates can be found in the Core Updates documentation.
