New and Updated Features

Drupal 9

Legacy Edge Shutdown Update

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.

New and Improved Workspace Switcher

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.

One-Click Database and PHP Upgrades

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.

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.
