Pantheon MU Plugin v1.5.3 release

The Pantheon MU Plugin v1.5.3 update is now available for Composer-based WordPress sites. For non-Composer-based WordPress sites, this latest update will be bundled with the next WordPress core update (likely 6.8, expected April 15.). WordPress (composer managed) sites can upgrade today using composer update or by checking for updates in the dashboard.

What's new?

The 1.5.3 update includes a number of minor bug fixes and enhancements:

• Updates all links to the Plugins with Known Issues documentation page to the updated WordPress Known Issues page to match the update to the docs site.
• Fixes a PHP warning on the Site Health page. (props to Weston Ruter for the report.)
• Fixes an issue in the compatibility layer that was causing the WP Rocket plugin to throw a fatal error on deactivation.
• Updates the compatibility layer to define constants earlier in WordPress execution. Previously, the constants were defined on plugins_loaded which may be too late to override those constants set by the plugins themselves. (props to Rachel Backert for the report.)
