The latest version of WordPress, 6.7 (Rollins), is available on Pantheon as of November 12, 2024.

Action required

Upgrade to WordPress 6.7 right from your Pantheon dashboard or Terminus to access the latest features, fixes, and security enhancements. See related documentation for how to apply core updates.

Highlights

• A new default theme, Twenty Twenty-Five, with dozens of customization options, templates, and patters built into the Site Editor.
• A new Zoom Out view to see more of your page layout at once.
• Updated style sections in the Site Editor to make it easier to customize your site design.
• ...and more

Check out the 6.7 preview we recorded with XWP on our YouTube channel.

Notes

• Support for HEIC images -- added in this version of WordPress -- will not be supported at release time on Pantheon due to a conflict with our version of ImageMagick. We are working on a solution that will include support for HEIC images in a future platform update.

For full details about WordPress 6.7, see the release notes or the WordPress 6.7 Field Guide.

We have rolled out a new site status block to improve visibility into software versions, helping customers track whether their site’s software is end-of-life (EOL).

Features and access

• Location: Access the status block via Pantheon dashboard > Site > Status.
• Software coverage: The block shows version information for PHP and Solr.

PHP version status

• PHP 8.0 and below are end-of-life. Upgrade to PHP 8.2 or above for full security coverage.

Solr version status

• Pantheon provides Solr versions 3 and 8. Version 3 is end-of-life. We recommend upgrading to Solr 8. Solr 8 support for Drupal 7 is in progress.

Redis recommendation

• Redis versions aren’t shown in the new block currently, but we recommend upgrading to Redis 6.2.

This addition helps you easily monitor and maintain your site's software for improved performance and security. For more information on other reports you can run on the Status tab, see the following:
