• Featured images associated with synchronized posts now also get deleted when the post is deleted
• A new filter ccb_core_synchronizer_delete_attachment has been created to optionally overwrite the default behavior of deleting attachments when posts are deleted
• Any images that are synchronized automatically get a post meta key of ccb_core with a value of true (in case you need to programmatically query for CCB images in the future)
