1.39.4
(fix): XML (TwiML) serialization drops characters outside the XML 1.0 Char production (e.g. \x01) from text and attribute values instead of emitting XML that no parser accepts.
1.39.3
(fix): XML (TwiML) types accept the declaration flag positionally, like the legacy TwiML gem:
response.to_s(false) and response.to_xml(false) omit <?xml ...?>; the xml_declaration:
keyword still works.
