\item The \class{Parser} constructor's \var{strict} argument was
added, and its \method{parse()} and \method{parsestr()} methods
grew a \var{headersonly} argument. The \var{strict} flag was
also added to functions \function{email.message_from_file()}

\item \method{Generator.__call__()} is deprecated; use
\method{Generator.flatten()} instead. The \class{Generator}
class has also grown the \method{clone()} method.
\item The \class{DecodedGenerator} class in the
\module{email.Generator} module was added.
\item The intermediate base classes \class{MIMENonMultipart} and
\class{MIMEMultipart} have been added, and interposed in the
class hierarchy for most of the other MIME-related derived
classes.
\item The \var{_encoder} argument to the \class{MIMEText} constructor
has been deprecated. Encoding now happens implicitly based
on the \var{_charset} argument.
\item The following functions in the \module{email.Utils} module have
been deprecated: \function{dump_address_pairs()},
\function{decode()}, and \function{encode()}. The following
functions have been added to the module:
\function{make_msgid()}, \function{decode_rfc2231()},
\function{encode_rfc2231()}, and \function{decode_params()}.
