Drupal 7 end of life is scheduled for the 5th of January 2025. After this date, there will be no more official updates and security and development patches for this system. Then your Drupal 7 website will be vulnerable to hacker attacks, and you’ll have to do all fixes on your own.
As Drupal experts, we always recommend having the latest version of this CMS because it means a safer system and new functionalities. Drupal 10 introduced significant improvements like a more modern and accessible appearance of the backend and frontend and the new WYSIWYG editor - CKEditor 5. The latest Drupal version is also based on the newer version (than in Drupal 8 and 9) of the Symfony framework.
