Description: 

Contact messages are now fieldable entities with the contact categories used as their bundles.

Contact messages are not persisted but fields can be added for each contact form (including the special form used for personal contact pages) and they are displayed in the sent e-mails. They implement Drupal\contact\MessageInterface.
