domain 4.0.0-alpha1

First release of the 4.x branch, for Drupal 11.4 and Drupal 12. It has the same features as 3.1, without the code 3.1 deprecated, and it includes the fix for SA-CONTRIB-2026-238.

Alpha releases are not covered by the Drupal security advisory policy. Sites that need that coverage should stay on 3.0.x.

Requirements

• Drupal ^11.4 || ^12. Sites on Drupal 10 or on Drupal 11 before 11.4 should stay on 3.0.x or 3.1.x.

Upgrading from 3.x

All database updates of 3.x are kept, so a site can update from 3.0.x or 3.1.x directly. Before you update, make sure your custom code runs on 3.1.0-beta1 without deprecation warnings from Domain: everything 3.x marked as deprecated for removal in 4.0.0 is gone.

What changed from 3.1

• Removed all code deprecated for removal in 4.0.0 (#3612485). This includes the old DomainNegotiator methods (use DomainResolver and DomainNegotiationContext, see #3583423 and #3575069), the DomainValidator methods replaced by constraints (#3574840), the procedural domain_source and domain_access functions replaced by their helper services, and the protected $domainStorage and $userStorage properties (use the domainStorage() and userStorage() methods, see #3612550).
• Removed DomainSourceRouteMatcher and its route provider: since Drupal 11.4, core gives the path processor the route (#3623227).
• Removed Drupal\domain\Form\DomainDeleteForm (#3615914).
• Plugins use PHP attributes only: the remaining plugin annotations are gone (#3541558), and the deprecated uri_callback entity type property is replaced (#3613276).
• Drupal 12 compatibility (#3612547, #3616749, #3616783, #3624244).
• Every bug fix released in 3.1.0-beta1 is also in this release.
