 === Features added
 
+* Cookie store support has been added. The `cookie_store`
+  option allows configuring the cookie store backend.
+  The `gun_cookies` module provides functions to help
+  implementing such a backend. Gun comes with the backend
+  `gun_cookies_list` which provides a per-connection,
+  non-persistent cookie store. The cookie store engine
+  implements the entire RFC6265bis draft algorithms except
+  the parts about non-HTTP cookies as no such interface is

+* HTTP/2 connection errors were missing the human readable

+* Fix the host and :authority (pseudo-)headers when connecting
