Description: 

Content entities may now declare UUIDs as a content entity's ID (though entity key mappings), removing the prior implicit requirement by core that all entities have separate UUIDs and IDs.

Example:

#[ContentEntityType(
  id: 'my_entity_type',
  entity_keys: [
    'id' => 'uuid',
    'label' => 'label',
    'langcode' => 'langcode',
    'uuid' => 'uuid',
  ],
  ... 
)]
Class MyEntityType extends ContentEntityBase {
}
