Pantheon release notes

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.

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

The latest versions of PHP 8.x are now available on the Pantheon platform. PHP 8.1.27, 8.2.16, and 8.3.3 are all bug fix releases. No action is required on your part if you are using one of these PHP versions (8.1, 8.2 or 8.3).

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.
