Drupal 10 Support Extended to December 2026; Deprecations Deferred to Drupal 13

The Drupal core team has established a definitive support schedule for Drupal 10, extending security and maintenance updates through December 2026 regardless of Drupal 12’s release date. This critical decision delivers a stable upgrade path and removes uncertainty for site operators and module developers.

Under the updated deprecation policy, disruptive deprecations —those that remove or replace widely used APIs —will be deferred to Drupal 13.0.0 instead of Drupal 12.0.0. This measure preserves backwards compatibility across the supported Drupal 10.5.x branch and the forthcoming Drupal 12 release.

Drupal 12 is scheduled to enter its first stable release window in mid-June 2026, with follow-up windows in early August and early December 2026. Security coverage for Drupal 10.5.x series will continue through June 2026, encompassing the beta and release candidate phases of Drupal 12.

Core modules designated for removal will transition to contributed packages after Drupal 11, ensuring a controlled migration path to Drupal 12. The official advisory contains detailed guidance on the deprecation policy, release schedule, and module migration procedures.
