It's not exactly a feature peak, but it is a new feature in Drupal that is still relatively unknown, so I'm writing about it.
Every time I created a social share image for my blog post in Canva, I had to change the file name after downloading to replace spaces with a middle dash, and convert uppercase letters to lowercase. However, starting with Drupal 10.2, this is no longer necessary. From this version onwards, there is an option for file name sanitization.
You can find this option on the following page: /admin/config/media/file-system.
