Some smaller changes made to the core Python language are:
+* :class:`bytes` and :class:`str` now have two net methods, *tranform* and *untransform*.
+ These provided analogues to *encode* and *decode* but are used for general purpose
+ string-to-string and bytes-to-bytes transformations rather than Unicode codecs.
+ Along with the new methods, several non-unicode codecs been restored from Python 2.x
+ including *base64*, *bz2*, *hex*, *quopri*, *rot13*, *uu*, and *zlib*.
+ >>> t = b'which witch had which witches wrist watch'
+ >>> t.transform('quopri')
+ >>> short = t.transform('zlib_codec')
+ >>> short.untransform('zlib_codec')
+ b'which witch had which witches wrist watch'
+ (From multiple contributers in :issue:`7475`.)
* The interpreter can now be started with a quiet option, ``-q``, to suppress
the copyright and version information in an interactive mode.
