Pantheon release notes

The integration between Pantheon and New Relic is being updated to ensure compatibility with the latest changes from New Relic. These updates will be seamless for most users, except for those who are using Quicksilver to interact with the New Relic API.

If you are using Quicksilver, particularly any of the three New Relic scripts in the quicksilver-examples repository, please update your scripts by June 20, 2024, to ensure continued functionality.

Action required: Get and store your user API key and update your scripts

The necessary updates are described in the README.md file for each script. The steps are:

1. Log in to the New Relic from your site dashboard.

2. Get a user key.

3. Store the user key using Terminus Secrets Manager plugin.

4. Update the script to the new version (don't forget to change the secret name as needed!).

5. Push your changes to your repo.

6. Test your scripts when you have a chance to ensure they are still working.

Our Support team is happy to help if you have any questions or need assistance.

Pantheon is moving the registration and login experience to utilize Auth0's Universal Login feature. This change will offer a more stable, modern, and secure first experience for new users.

The latest 1.4.4 update of the Pantheon MU Plugin and the 2024-06-04 release of the WordPress (Composer Managed) are now available.

The MU plugin update will be included with the WordPress 6.5.4 release.

What's new?

Pantheon MU Plugin 1.4.4

This update fixes the WordPress Multisite network setup process by by ensuring the correct instructions for WordPress Multisite setup on Pantheon environments are always shown. The MU plugin replaces the WordPress core network setup page with a custom page that provides instructions for setting up a multisite network on Pantheon and adds filters that allows the content to be changed.

This update also fixes some display issues to that page.

WordPress (Composer Managed) update

The 2024-06-04 WordPress (Composer Managed) (Early Access) release updates the configuration file filename displayed on the network setup screen to specify config/application.php to apply your configuration changes to (the Bedrock default), rather than the WordPress default wp-config.php. This is accomplished via a filter in the MU plugin's implementation of that admin page that allows the configuration file name to be modified.

This update is now available to all WordPress (Composer Managed)-based installs.

The WordPress (Composer Managed) update also includes a Composer script to automatically update the Composer platform.php value to match the version of PHP in your pantheon.yml. Note: Roots Bedrock does not support below PHP 8.0. This update is unrelated to WordPress multisites, but is included in the latest release for the WordPress (Composer Managed) upstream.

The new 2.0.0 release is now available for the Pantheon Advanced Page Cache WordPress plugin. This update makes significant changes to the UI of the Pantheon Page Cache admin settings page when installed on a Pantheon environment with the latest version of the Pantheon MU Plugin (1.4.3 or later).

Highlights

• UI improvements: The Pantheon Page Cache admin settings page simplifies the Cache Max Age setting, providing a dropdown with values for 1 week, 1 month and 1 year. If a different value was saved in the database, it will be displayed as "Custom" in the dropdown with a humanized representation of the time. This is an improvement over the base input in the Pantheon MU plugin which requires a value in seconds. These changes will be available when the 1.4.3 release of the Pantheon MU plugin is deployed alongside WordPress 6.5.4.
• Site Health integration: Pantheon Advanced Page Cache now integrates into the Site Health page in your WordPress admin. Tests are run and reported for your cache max age value and recommendations are made.
• Minimum WordPress version bumped to 6.4: This update requires WordPress 6.4 or later for integration with the Site Health page and usage of the new wp_admin_notice function. If you are running an older version of WordPress, the plugin will still function, but a warning will be given on the Plugins page and you will not benefit from the updated notices and Site Health checks.
• Max age updated if previously saved at 10 minutes: The previous cache max age default value was 600 seconds. We currently recommend a minimum of 1 week for best performance, especially when using Pantheon Advanced Page Cache (which will automatically flush the cache when content is updated). If you had previously saved the default value of 10 minutes, it will automatically be updated to 1 week when you update to this version and log into the WordPress admin.
• Integration with the pantheon_cache_default_max_age filter: Pantheon Advanced Page Cache supports the pantheon_cache_default_max_age filter added in the Pantheon MU Plugin 1.4.0. If you have set a default max age with the filter for your site, Pantheon Advanced Page Cache will respect that value and display it in the UI as a custom value.

Download the 2.0.0 update today from your WordPress admin or from the WordPress plugin repository. Composer-based WordPress sites can get the update by checking the version parameters in your composer.json (ensuring that the version string is set to "*" or "^2.0") and running composer update.
