Pantheon release notes

The New Relic PHP agent has been updated to the latest version, v11.2.0.15, for all eligible versions of PHP. Support for PHP 7.0 and 7.1 was removed in version 11.0, so the New Relic PHP agent for those versions remains at v10.22.0.12.

This update brings several enhancements and fixes compared to the previous version, including support for Drupal 11. Note, New Relic agent 11.2 introduces information collection for Composer packages, but this is not yet enabled on Pantheon.

For a detailed list of all changes and improvements, see the complete New Relic PHP agent changelog.

Pantheon has committed to provide security updates to Drupal 7 sites for at least 2 additional years beyond it's upcoming end of life date on January 5, 2025. Pantheon is partnering with Tag1 Consulting to offer Long-Term Support (LTS) for Drupal 7 at no additional cost through at least January 5, 2027.

To learn more about whats included in this offering, see related documentation.

Drupal 11 is now available as an option when creating a new Drupal site on Pantheon. Previously, in order to create a new Drupal 11 site you had to first create a Drupal 10 site and then manually upgrade to Drupal 11 via Composer.

See related documentation for how to create new CMS sites on Pantheon.

PHP 8.1.30, 8.2.24 and 8.3.12 were released on the platform. They contain the latest bug fixes and security updates for PHP.

As a reminder, PHP 8.0 reached End-of-Life and PHP 8.1 was moved to security-only updates on 26 November 2023. PHP 8.1 will reach End-of-Life in December 2025. For the best performance and security, Pantheon recommends running PHP 8.2 and above.

• PHP Supported Versions

With the Terminus 3.6.0 release, you can now rename site labels directly through Terminus using the new site:label:set command. Previously, updating a site's label required contacting Support.

A site on Pantheon has both a machine name and a human-readable label:

• Machine name (e.g., my-awesome-site): Used in Terminus commands, constructs platform domains, and cannot be changed after site creation.
• Human-readable label (e.g., My Awesome Site): Shown in the Pantheon workspace and site dashboards. This label can be changed after site creation via Terminus. For example:

Upgrade today to take advantage of this new command.

How to upgrade Terminus

If you manage your installation via Homebrew on macOS, you can update Terminus with the following command:

For other systems, see additional upgrade instructions here.

Tracking of command success rates and execution time (#2623).

RSS readers will now detect multiple release notes from the same date.

Our release note publishing process runs through Markdown and Git with published dates set manually only at the granularity of year, month, and day. RSS readers (like our Community Slack integration) ignore multiple items with identical dates and times. We have worked around this limitation by setting an arbitrary hour, minute, and second for each release note within the RSS feed by deriving a hash of the note.

To reduce the pain of adding custom domains for our Diamond and Platinum customers, sites associated with Diamond and Platinum workspaces are now automatically exempt from domain verification enforcement. Exemption enables the option to skip domain verification when connecting custom domains in the site dashboard. Previously, this exemption had to be requested by contacting support.

We're thrilled to announce the availability of WP-CLI v2.11.0 on the Pantheon platform.

WP-CLI is easily accessible for any WordPress site on Pantheon through our CLI, Terminus, allowing you to manage your WordPress installations efficiently with WP-CLI’s powerful commands at your fingertips.

Highlights

• New site generator command: This new command has been added to create multiple sites programmatically in a multisite installation. This is useful for testing or development purposes.

• GitHub release installation support: The extension command now supports installing plugins and themes directly from GitHub releases.

• Minor and patch limitations for theme updates: Themes can now be updated only to their latest minor or patch releases, similar to plugins.

• New "user exists" command: A new wp user exists command allows for quick checks on whether a user exists in the WordPress database.

• Option to delete unknown image sizes: The new --delete-unknown flag added to wp media regenerate is especially helpful for site owners dealing with highly populated media directories.

• Bug fixes: WP-CLI 2.11.0 includes numerous bug fixes, with over 250 pull requests merged, addressing both minor and significant issues.
