This means that when - a suitable coercion target locale is available, both the core interpreter and - locale-aware C extensions will assume the use of UTF-8 as the default text - encoding, rather than ASCII. - -- bpo-30486: Allows setting cell values for __closure__. Patch by Lisa Roach. - -- bpo-30537: itertools.islice now accepts integer-like objects (having - an __index__ method) as start, stop, and slice arguments - -- bpo-25324: Tokens needed for parsing in Python moved to C. ``COMMENT``, - ``NL`` and ``ENCODING``.
