On Sunday (July 12), UNL CMS was upgraded to Drupal 11. The editing interface in the new system is the same as is was in Drupal 10, with most key feature changes related to security and performance.
In addition to these core changes, updates to CKEditor (WYSIWYG editor) and file and media management will allow feature enhancements (such as additional table and text styling, further image optimization, and other speed enhancements) that the previous version did not.
