This week, Dries announced at DrupalEurope, and on his blog, that November 2021 will be the End of Life (EOL) date for both Drupal 7 and Drupal 8. Drupal 9 is now scheduled to be released in 2020, giving people a year to upgrade from version 8 to version 9 before Drupal 8's EOL. Why is Being on a Supported Version Important? Because being on a version of Drupal that's "no longer supported" means that it will not be updated when new security vulnerabilities are discovered. How does this affect resource-constrained nonprofits using Drupal?
