Drupal 10 is released on December 14, 2022. The end of life of Drupal 9 is not scheduled until the end of 2023 to provide some margin.
With a new release in 2022 and Drupal 9 end of life by the end of 2023, Drupal 9 is expected to have the shortest lifespan among Drupal major releases in recent history. The most important new feature for you is that user-friendliness has been increased again.
