db_maintenance 3.1.0-alpha1

First alpha of the 3.1.x branch, the new development line of DB Maintenance. It has the same features as 3.0.0 and differs only in the Drupal core versions it supports.

Drupal 12 only

• 3.1.x requires Drupal 12 (core_version_requirement: ^12).
• Sites on Drupal 8, 9, 10 or 11 stay on the 3.0.x releases, which continue to support those versions as well as Drupal 12.

Changes since 3.0.0

• Raised the minimum core version to Drupal 12.
• Removed the procedural hook functions and the db_maintenance.module file. Hooks are implemented only in the DbMaintenanceHooks class through the #[Hook] attribute.
• Removed db_maintenance.services.yml. Drupal core registers the hook class on its own.
• The MySQL and PostgreSQL handlers call FetchAs::Associative and Error::logException() directly instead of checking whether they exist.

Upgrading from 3.0.0

• No configuration changes, no schema changes and no database updates.
• Rebuild caches after updating the code, because a service definition and the .module file were removed.
• Custom code that calls db_maintenance_cron() or db_maintenance_help() directly will break; those functions no longer exist.

Testing

Tested against Drupal 12.0.0-beta1 on PHP 8.5 and PostgreSQL 18. This is an alpha release for a core version that is itself still in beta.
