Drupal is a free, open-source, flexible, and secure content-management framework for website development. 
It handles large and complex websites very well. 

Twenty-three years after Drupal's inception, we are preparing to launch a second official version of Drupal. 
For the time being, we're calling this second version "Drupal CMS".

Drupal is a free and open-source content-management framework that can be customized and is suitable for developing simple websites or complex web applications. 

Drupal has been found to have a lower approval rating among new users compared to expert users. 
This led to an initiative being launched by Drupal's founder, Dries Buytaert, to address the needs of beginner users. 

Multiple security updates have been released today for contributed modules on drupal.org. 
If you use the REST Views or Advanced Progressive Web App (PWA) modules, you should update as soon as possible to ensure your site's security.

Drupal is a powerful, open-source content management system that has been serving users for over two decades. 

On the surface, this doesn't make sense. Any average D10 site is probably one of the most complex #symfony apps in the world. When Drupal 8 was being built, I remember how the community found and patched a ton of edge case bugs in PHP and Symfony because it is SO BIG and so complex.
