drupal 9.4.0-rc2

This is a release candidate for the next minor version (feature release) of Drupal 9. Release candidates are not supported for production sites, but they are intended for widespread testing in preparation for the upcoming stable release. More information on release candidates.

This release fixes security vulnerabilities. Sites are urged to update immediately after reading the notes below and the security announcements:

• Drupal core - Moderately critical - Third-party libraries - SA-CORE-2022-011

This minor release provides new improvements and functionality without breaking backward compatibility (BC) for public APIs. Note that there may be changes in internal APIs and experimental modules that require updates to contributed and custom modules and themes per Drupal core's backwards compatibility and experimental module policies.

Drupal 9.4.x contains new features, and should be the target for new site development. Drupal 9.3.x will continue to have security support until December 2022. Security support for 9.2.x ends with the release of 9.4.0 on June 15, 2022.

Important update information from 9.4.0-rc1

• Drupal 9.4 core now requires guzzlehttp/guzzle 6.5.7 or higher (up from 6.5.6), or 7.4.4 or higher (up from 7.4.3).

• No changes have been made to the .htaccess, web.config, robots.txt, or default settings.php files in this release, so updating custom versions of those files is not necessary if your site is already on the previous release.
