-* Fix `ServerRequest::getUriFromGlobals` when `Host` header contains port.
-* Ensure `ServerRequest::getUriFromGlobals` returns a URI in absolute form.
-* Allow `parse_response` to parse a response without delimiting space and reason.
-* Ensure each URI modification results in a valid URI according to PSR-7 discussions.
-  Invalid modifications will throw an exception instead of returning a wrong URI or
