(From multiple contributors in :issue:`7475`.)
* String formatting for :func:`format` and :meth:`str.format` gained a new format
character **#**. For integers in binary, octal, or hexadecimal, it causes
the output to be prefixed with '0b', '0o', or '0x' respectively. For floats,
complex, and Decimal, it causes the output to always have a decimal point
even when no digits follow it.
>>> format(20, '#o')
'0o24'
>>> format(12.34, '#5.0f')
' 12.'
(Suggested by Mark Dickinson and implemented by Eric Smith in :issue:`7094`.)
* The interpreter can now be started with a quiet option, ``-q``, to suppress
the copyright and version information in an interactive mode.
