Pantheon release notes

Terminus 3.0 is now available. Use Terminus to perform any task you might do in the Pantheon Dashboard, including actions via Drush and WP-CLI. In addition, patch releases for Terminus 3 and Terminus 2 have also been released.

Customers can now upgrade their site database and PHP by using the One-Click Upstream Update feature in the Site Dashboard or the command Terminus upstream:updates:apply. Pantheon makes it simple to keep your site database secure and performant. Sites using Custom Upstreams can easily upgrade to supported database versions by configuring the site's pantheon.yml.

The usability of Workspace Switcher in the New Dashboard has been improved. The switcher in the Primary Global Navigation is now optimized for large accounts and will allow users to search for a Workspace directly in the New Dashboard. You can view up to 10 Workspaces connected to your account, from the list in the Primary Global Navigation.

As part of our end-of-life plan to retire the Legacy Edge, CNAMEs edge.live.getpantheon.com and styx-01.pantheon.io now point to Global CDN.  This change allows for the transition of sites to Global CDN with minimal interruption. Permanent shutdown happens on February 1, 2022.

Drupal 9 is in General Availability! It is available on Pantheon to all new sites, and is available as an upgrade path from Drupal 8 with Integrated Composer. For more information, refer to the documentation.

Convert a Custom Upstream to Integrated Composer - Learn how to convert a non-Composer-managed Drupal 8 site to Integrated Composer while on Drupal 8. The process is similar to the Upgrade Pantheon Drupal 8 Sites to Drupal 9 With Integrated Composer guide, except that you will stay on Drupal 8 with some special considerations for Custom Upstreams, and can defer the Drupal 9 upgrade to later. Refer to the documentation for more information.

WordPress 5.8.2 is available on the Pantheon platform. Detailed information on applying and debugging core updates can be found in the Core Updates documentation. This security and maintenance release features two bug fixes in addition to one security fix. Because this is a security release, it is recommended that you update your sites immediately. All versions since WordPress 5.2 have also been updated. This release fixes security vulnerabilities and users are urged to upgrade their sites immediately.

Drupal 9.2.8 is now available for production sites. Drupal 9 sites on Pantheon use Integrated Composer, enabling one-click core updates through the Dashboard. To check for available updates, click Check Now from the Site Dashboard Dev tab.

Drupal 9.2.x will receive security coverage until June 15, 2022. Sites on 9.1.x or earlier should update to Drupal 9.1.13.
