-Added :class:`email.parser.BytesHeaderParser`.
+New :class:`~email.parser.BytesHeaderParser`, added to the :mod:`~email.parser`
+module to complement :class:`~email.parser.HeaderParser` and complete the Bytes
+API.
+
+New utility functions:
+
+   * :func:`~email.utils.format_datetime`: given a :class:`~datetime.datetime`,
+     produce a string formatted for use in an email header.
+
+   * :func:`~email.utils.parsedate_to_datetime`: given a date string from
+     an email header, convert it into an aware :class:`~datetime.datetime`,
+     or a naive :class:`~datetime.datetime` if the offset is ``-0000``.
+
+   * :func:`~email.utils.localtime`: With no argument, returns the
+     current local time as an aware :class:`~datetime.datetime` using the local
+     :class:`~datetime.timezone`.  Given an aware :class:`~datetime.datetime`,
+     converts it into an aware :class:`~datetime.datetime` using the
+     local :class:`~datetime.timezone`.

+The :func:`~logging.basicConfig` function now supports an optional ``handlers``

+A class level attribute :attr:`~logging.handlers.SysLogHandler.append_nul` has
