This is a patch (bugfix) release of Drupal 9 and is ready for use on production sites. Learn more about Drupal 9.
Drupal core uses the third-party Diactoros library as its PSR-7 implementation. Diactoros has issued a security advisory:
Drupal core is unlikely to be vulnerable. This bugfix release updates the version of Diactoros used in drupal/core-recommended to a secure version as a precaution. As a reminder, Drupal 9.4 and higher sites should update their third-party Composer dependencies when an upstream security advisory is issued.
Drupal 9.4.x will receive security coverage until June 2023.
If you are upgrading from Drupal 8, read upgrading a Drupal 8 site to Drupal 9, 9.0.0 release notes, and the 9.4.0 release notes before upgrading to this release.
Important update information
Drupal no longer specifies core modules in the 'replace' section of composer.json. This allows contributed versions of core modules to be downloaded with the canonical namespace using Composer.
Following the development of Drupal 9.4.0, we have discovered PHP versions 8.1.0-8.1.5 have a bug with the PHP OPcache that may cause intermittent fatal errors at runtime for class autoloading. Since PHP 8.1.6 is recent it may not yet be available on hosting platforms, the minimum recommended PHP version for Drupal 9.4 has been lowered to 8.0. PHP 8.1.6 or higher is still the best choice for forward-compatibility with Drupal 10.
Previously, plugin settings for all CKEditor plugins were stored in the editor configuration. This included disabled plugins.
To keep the editor configuration in a consistent state, plugin settings are now only stored for CKEditor plugins that are enabled. Stored editor configuration entities will be updated in this release to remove the disabled plugin data.
To ensure CKEditor data is upgraded to CKEditor 5 correctly, sites should update to this release prior to updating to Drupal 10.
The CKEditor 4 to 5 upgrade path no longer checks if a plugin is enabled before migrating its config. Sites should update to Drupal 9.4.4 or higher prior to updating to Drupal 10, and should ensure
update.phpis run. This will ensure disabled CKEditor 4 plugins do not have their config stored.The pinned version of
laminas/laminas-diactoroshas been updated from 2.8.0 to 2.11.1.
