Today announcement came out:
Therefore, we are announcing that moving forward, the scheduled Drupal 7 End-of-Life date will be re-evaluated annually. As of today, we are extending the end-of-life by one year to November 1, 2023.
Shows respect for a huge community that cannot afford to move to D9.
More than a decade after its first release, Drupal 7 is still widely used across the web. It can be found powering civic engagement in government installations; managing vast amounts of content for faculty, students, and staff in educational institutions; and providing the digital backbone for many businesses and non-profit organizations. Drupal 9 is well-maintained, secure, stable, and feature-rich, but many organizations still rely on Drupal 7.
The teams that built and still maintain these legacy Drupal installations, and the end users they serve, are important constituents of the Drupal community. Although these users should still plan their upgrade to a newer version of Drupal, if they are unable to upgrade before the currently announced end-of-life, it would not be responsible of us to leave them vulnerable.
Thank you, Drupal Association, for keeping community a priority.
