Pantheon release notes: WordPress

April 15, 2024

An update is now available for the WordPress (Composer Managed) upstream to resolve a particular log message that started appearing after our WP-CLI wrapper update in February.

This update adds a new file to the /config directory, application.pantheon.php. In order to accomodate this new file, a line has been added to config/application.php to load the config/application.pantheon.php file. If you have made modifications to your config/application.php, it's possible you may run into conflicts with this update. If this is the case, you can manually resolve by running the following command:

git pull -Xtheirs https://github.com/pantheon-upstreams/wordpress-composer-managed.git main
git push origin master

For more help or assistance about managing potential merge conflicts, refer to our documentation on auto-resolving via the dashboard or manually resolving via the command line.

Technical Details

The application.pantheon.php file curently contains code to check for a defined WP_HOME value in the site's .env file. If the value is undefined or no .env file is being used, values for WP_HOME and WP_SITEURL are defined. This can be overridden by either adding values to the site's .env file or adding putenv( 'WP_HOME=https://example.com' ); and putenv( 'WP_SITEURL=https://example.com' ); to your application.php file.

Why the change?

Roots Bedrock makes heavy use of environment variables. We made an intentional decision to not rely on .env files in order to reduce overall complexity. This left WP_HOME and WP_SITEURL undefined in the application.php file except in local development with Lando. In most cases, WordPress is intelligent enough to use the database values for home and siteurl for normal interactions, however, this caused problems with WP-CLI operations. The addition of a new application.pantheon.php file allows us to define those values if they are not already while still allowing them to be overridden for more complex environments.

April 10, 2024

The latest version of WordPress, 6.5.2, became available on Pantheon as of April 10, 2024.

Highlights

What happened to 6.5.1?

6.5.2 is the first minor release for WordPress 6.5 rather than 6.5.1. Yesterday, it was disclosed on the Make WordPress Core development site that due to an error with the initial package, 6.5.1 could not be released.

Upgrade to WordPress 6.5.2 right from your Pantheon dashboard or Terminus for added security.

April 2, 2024

The latest version of WordPress, 6.5 (Regina), became available on Pantheon as of April 2, 2024.

Highlights

Font Library
  • WordPress 6.5 introduces the new Font Library. This feature allows you to upload fonts to your WordPress site or install any of the fonts available from Google's font library.
  • Previously, in version 1.3.3 of our Pantheon MU Plugin, we added support for the new Font Library feature by explicitly defining where fonts are stored to support this new feature.
  • For more information, refer to our documentation.
Interactivity API
  • WordPress 6.5 also adds a new Interactivity API. This API establishes a standardized way to add interactive elements to Gutenberg blocks.
Performant Translations
  • A new localization system has been introduced in WordPress 6.5 to improve the performance of translations. This system uses a new file format, .l10n.php, to store translations in addition to the standard .mo and .po files you may already be familiar with. When .l10n.php files exist, they are loaded instead, providing significant performance improvements and using less memory.
  • For more information about Performant Translations on Pantheon and how to generate .l10n.php files if they do not exist, see our Performant Translations guide.
Plugin Dependencies
  • WordPress plugins can now have dependencies on other plugins. This allows plugin authors to specify that their plugin requires another plugin to be installed and activated in order to work properly. A new Requires Plugins Plugin Header has been introduced to require other plugins to be installed and activated before the current plugin can be activated and prevent plugins that are dependent upon other plugins to be deactivated accidentally. For more information, see the Plugin Dependencies dev note.
...And More
March 27, 2024

On March 25, 2024, it was announced in the WordPress development blog that the default storage location for the Font Library (added in WordPress 6.5) will be wp-content/uploads/fonts. Previously, we had added a feature to our Pantheon MU Plugin to support the new Font Library feature by changing the previous default path (wp-content/fonts) to wp-content/uploads/fonts. This change to our MU plugin removes that override as it is no longer necessary. You can read more about the Font Library feature in our guide to using the Font Library on Pantheon.

March 11, 2024

Pantheon Advanced Page Cache v1.5.0 is now available on WordPress.org and GitHub. This release adds a new filter to make cache purges less aggressive and provide more flexibility for developers and the sites they maintain. You can learn about the filter in the plugin's README file which includes an example of how to use it.

Additionally, this update implements our recently updated WPUnit Helpers project to simplify PHP Unit tests as well as our recently developed Plugin Release Actions to automate steps in the release process.

You can read the full changelog in the GitHub release notes.

March 4, 2024

WordPress 6.5 will add a new Font Library feature. The Font Library allows you to upload fonts from your computer or add any of the fonts available on Google's font library to your WordPress site. In anticipation of this, Pantheon has added a feature to our Pantheon MU Plugin to support the new Font Library feature. You can read more about the Font Library feature in our guide to using the Font Library on Pantheon.

February 27, 2024

We've recently modified the Pantheon wrapper around the WP-CLI executable to solve a number of interrelated issues that customers may have previously been experiencing and/or using workarounds to solve. We recommend reviewing your site's logs and resolve any PHP notices or warnings.

Problem

  • Our WP-CLI wrapper included a hard-coded --url flag for all wp commands run on the platform (via Terminus, e.g. terminus remote:wp or terminus wp, or internal workflows that relied on WP-CLI like flushing cache or viewing the Status page in the dashboard).
  • For WordPress Multisites, the hard-coded --url flag pointed to the Pantheon platform domain (*.pantheonsite.io) instead of the actual domain of the site resulting in errors and the command failing unless executed manually (via Terminus with the correct --url flag attached).

Solution

  • We have implemented a solution that checks if a site is a WordPress Multisite. If so, we remove the hard-coded --url flag, allowing WP-CLI to operate normally.
  • This change does not affect workflows that are properly passing the --url flag to WP-CLI commands via terminus (e.g. terminus wp <site>.<env> -- plugin list --url=<url>). Any WP-CLI flags passed after the -- in the terminus wp command will be passed through to and interpreted by WP-CLI.
  • This change means that many sites that were previously unable to view their full Status page will now be able to do so, and flushing site cache via the button in the Pantheon dashboard on sites that previously were unable to or had errors in doing so should now work as expected. Any other workflows or processes that relied on WP-CLI will also benefit from this change.

Recommended action

This change may also expose PHP notices and warnings that were previously being hidden due to WP-CLI failing commands. We recommend reviewing your site's logs and working to resolve any PHP notices or warnings that you see.
February 20, 2024

We're thrilled to announce the availability of WP-CLI v2.10.0 on the Pantheon platform.

WP-CLI is easily accessible for any WordPress site on Pantheon through our CLI, Terminus. Manage your WordPress installations efficiently with the power of WP-CLI at your fingertips.

Highlights

  • New i18n "make-php" command: This new command lets site owners take advantage of WordPress Core's "Performant Translations" project even before it is released with WordPress Core.
  • Adds minor and patch limitations to theme updates: Now, like plugins, themes can be updated only to their latest minor or patch releases
  • Bug fixes: WP-CLI 2.10.0 fixes "a lot of small and not so small bugs" with more than 200 pull requests merged.

For those who love diving into the details, we encourage you to explore the detailed WP-CLI changelog.

January 31, 2024

The latest version of WordPress, 6.4.3, became available on Pantheon as of January 30, 2024.

We're thrilled to announce the availability of WP-CLI v2.9.0 on the Pantheon platform.

Highlights

  • Enhanced PHP 8.2 support: This release is dedicated to refining support for PHP 8.2, the recommended version on Pantheon.
  • Optimized compatibility with WordPress 6.4: We've worked to guarantee seamless compatibility, providing you with the best performance and features available.
  • Introducing "wp config is-true" command: Our Pantheon engineers have introduced the new "wp config is-true" command. Specifically designed for shell scripting, this command improves WP-CLI functionality and is already integrated into some of our automation processes.
  • Bug fixes: Although primarily a compact release, WP-CLI v2.9.0 brings a significant impact with crucial bug fixes to enhance usability.

For those who love diving into the details, we encourage you to explore the detailed WP-CLI changelog.

January 23, 2024

The latest version of WordPress, 6.4.2, became available on Pantheon as of December 6, 2023.

  • 7 bug fixes in Core: Resolved an issue causing inconsistencies in stylesheet and theme directories.

Upgrade to WordPress 6.4.2 right from your Pantheon dashboard or Terminus for added security.
