New Features
Certain top-level domains (TLDs) such as .dev and .app are now in the Foundation URLSession and NSURLConnection HTTP Strict Transport Security (HSTS) preload list. An app which uses URLSession to visit a matching URL will always navigate to the URL as https://, and never as cleartext http://. See the HTTP Strict Transport Security (HSTS) Specification for more information about HSTS. (56247242)
