Pantheon is announcing a PHP version removal schedule. The following PHP versions will be removed from the platform on September 30, 2026:

  • PHP 5.6
  • PHP 7.0
  • PHP 7.1
  • PHP 7.2 (End of Sale: May 1, 2026)
  • PHP 7.3 (End of Sale: May 1, 2026)
  • PHP 8.0 (End of Sale: May 1, 2026)

PHP 5.6, 7.0, and 7.1 are already end-of-sale. PHP 7.2, 7.3, and 8.0 will reach end-of-sale on May 1, 2026, meaning no new sites can be created with these versions after that date.

Additionally, PHP 8.1 will reach end-of-sale on September 30, 2026, with a removal date to be announced at least 9 months in advance.

What happens when a PHP version is removed?

Sites still running a removed PHP version will be automatically upgraded to the oldest available PHP version at the time of removal. If your site's software has not been updated for compatibility, this may result in broken functionality.

What to expect going forward

Pantheon will guarantee at least 9 months of advance notice before removing any PHP version from the platform. Refer to the PHP version lifecycle table for the latest schedule.

Action required

If your site is running PHP 5.6, 7.0, 7.1, 7.2, 7.3, or 8.0, upgrade to a recommended PHP version before September 30, 2026 to avoid disruption. We recommend PHP 8.3 or 8.4 for all production sites.

For guidance on upgrading, refer to Upgrade PHP Versions.

The Next.js site creation process now includes prompts for setting secrets at site creation time. This change benefits sites that need API tokens or other variables in order to build successfully. Previously, sites requiring these secrets would fail their automatic first build.

Setting secrets at site creation

Secrets set in this interface are stored securely using Pantheon's Secrets Manager.

The ability to set secrets at site creation time is valuable for anyone standing up our Content Publisher integration. See this updated tutorial that shows secret-setting at site creation.

Pantheon has released version 2.3.1 of the WP SAML Auth WordPress plugin. This update adds a new filter for multisite environments to give developers more control over how SAML-provisioned users are added to sites. No action is required — existing behavior is unchanged.

What's new

  • Multisite user provisioning control — A new wp_saml_auth_auto_add_to_blog filter allows developers to prevent auto-provisioned SAML users from being automatically added to the current site. When set to false, users are created as network-level users without a role on any specific site, giving full control over site membership. The filter defaults to true, preserving existing behavior. See #465 for details.
Information:
Developer note

If you use the new wp_saml_auth_auto_add_to_blog filter and return false, the user passed to the wp_saml_auth_new_user_authenticated action will have no role on the current site. Any hooks relying on $user->roles being non-empty should account for this.

Update to 2.3.1 from the WordPress dashboard under Plugins > Installed Plugins, or download it from the WordPress Plugin Repository.

For more details, see the plugin changelog.

March 6, 2026

The Drupal CMS upstream has been updated to version 2. Newly created sites using the Drupal CMS upstream will now use Drupal CMS 2, which includes a curated set of modules and configuration designed to help you get started faster.

This update only applies to sites created with the Drupal CMS upstream. Sites using the Drupal 10 or Drupal 11 upstreams are not affected. Existing Drupal CMS sites are also not affected — refer to the Drupal CMS documentation for upgrade guidance.

Our documentation has instructions on how to configure a new Drupal CMS site.
