Pantheon release notes

Drupal 8.9.3 is now available on the Pantheon platform. Detailed information on applying and debugging core updates can be found in the Core Updates documentation. For more information, see the Drupal 8.9.3 release notes.

Pantheon’s Multidev and COVID Response site offers have been extended to Sept 1, 2020.

Drupal 9 is available for early access testing with new or existing sites. We don't recommend fully switching a live site to Drupal 9 until we have upgraded our version of MariaDB.

Drupal 8.9.2 is now available on the Pantheon platform. Detailed information on applying and debugging core updates can be found in the Core Updates documentation. For more information, see the Drupal 8.9.2 release notes.

All Pantheon customers are now provisioned with a dedicated certificate for HTTPS for each custom domain on a site environment. In addition, the go-live experience has been optimized and now lets you configure HTTPS before launch via the DNS TXT method to verify domain ownership.

WordPress 5.4.2 is now available on the Pantheon platform. As part of this release, Pantheon also rolled out a configuration change to block xmlrpc by default. If your site uses xmlrpc, re-enable it before deploying this release to production.

Although it places load on the platform, Pantheon now excludes traffic from Petalbot, which would otherwise count towards your website's total traffic.

Terminus 2.4.0 has been released. See the release notes for more information.
