 ### Minor Changes
 - Added loose mode to the serialized options. Now a serialized cookie jar with loose mode enabled will honor that flag when deserialized.
 - Added allowSpecialUseDomain and prefixSecurity to the serialized options. Now any options accepted passed in to the cookie jar will be honored when serialized and deserialized.
+- Added handling of IPv6 host names so that they would work with tough cookie.
