drupal 9.3.0-rc1

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 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 9.3.x contains new features, and should be the target for new site development. Drupal 9.2.x will continue to have security support until June 2022.

Drupal 8.9.x security coverage ended in November 2021, so if you are using Drupal 8, you must upgrade as soon as possible to Drupal 9.2.x or Drupal 9.3.x to keep your site secure.
