If your site is one of the > 600,000 live sites currently on Drupal, you are probably aware of Drupal 9, launched June 3, 2020.
This latest release and the future end of life for Drupal 7 (extended to November 2022) and Drupal 8 (November 2021) will evolve the Drupal platform to fully integrate with Symfony as the underlying framework, the first Drupal 9 release requires a more recent release of Symfony, version 4.4. This brings enhancements to the framework that Drupal code and module developers can leverage to advance and develop new features. Drupal 8 will reach end-of-life due to its dependence on Symfony 3.4, which is scheduled for the end of life in November 2021.
