drupal 10.6.0-rc1

This is a release candidate for the next maintenance minor release of Drupal 10. 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 maintenance minor provides important dependency updates and API additions for Drupal 10 sites to provide the best forward-compatibility with Drupal 11. It does not break backward compatibility (BC) for public APIs. This is according to Drupal core's backward compatibility and experimental module policies.

Drupal 10.6.x will receive security support until December 2026. Drupal 10.5.x will continue to receive security support until June 2026.

Drupal 10.4.x security support has ended. Sites on any Drupal version prior to 10.5.x should upgrade to a supported release as soon as possible.
