Happy weekend! Due the latest news we have a single change for your own safety. iris.AutoTLS users should pass all the necessary information now, these are the recommended by letsencrypt.

Iris devs should declare all the information now, there is no option to "leave something out" anymore, it's for your own good. Version is not changed yet, giving you time to see that changelog and do the necessary changes to your codebase. Happy weekend!
