There are several new features in the latest 10.13.4 update. One thing that might have slipped your attention is the new notice in the Safari web browser if you are on a website that is insecure. Safari shows “Website Not Secure” in your browser address area. This article shows how it works. I think this is a good thing. At least you know when you are on an insecure website. That is a big deal depending on what type of site it is.
