SSL Certification no longer required

SSL Certificates are no longer required is that correct? but the prefix WWW will no longer work?

These only apply to free subdomains

Ok thanks my certificate runs out in a few days - do I need to do anything to ensure Https still works. It sounds like no but i want to be 100%

If you are using a free subdomain, then you do not need to worry about SSL certificates. HTTPS will continue to work even if the old certificate expires; just be sure to visit without the “www” prefix.

However, if you are using a custom domain, then you will still need to renew your SSL certificate every 90 days, or before it expires as usual.
