7.1.0
-----
* New itertools
* :func:`ichunked` (thanks davebelais and youtux)
* :func:`only` (thanks jaraco)
* Changes to existing itertools:
* :func:`numeric_range` now supports ranges specified by
``datetime.datetime`` and ``datetime.timedelta`` objects (thanks to MSeifert04 for tests).

7.0.0
-----
* New itertools:
* :func:`time_limited`
* :func:`partitions` (thanks to rominf and Saluev)
* :func:`substrings_indexes` (thanks to rominf)
* Changes to existing itertools:
* :func:`collapse` now treats ``bytes`` objects the same as ``str`` objects. (thanks to Sweenpet)
The major version update is due to the change in the default behavior of
:func:`collapse`. It now treats ``bytes`` objects the same as ``str`` objects.
This aligns its behavior with :func:`always_iterable`.
.. code-block:: python
>>> from more_itertools import collapse
>>> iterable = [[1, 2], b'345', [6]]
>>> print(list(collapse(iterable)))
[1, 2, b'345', 6]
6.0.0
-----
* Major changes:
* Python 2.7 is no longer supported. The 5.0.0 release will be the last
version targeting Python 2.7.
* All future releases will target the active versions of Python 3.
As of 2019, those are Python 3.4 and above.
* The ``six`` library is no longer a dependency.
* The :func:`accumulate` function is no longer part of this library. You
may import a better version from the standard ``itertools`` module.
* Changes to existing itertools:
* The order of the parameters in :func:`grouper` have changed to match
the latest recipe in the itertools documentation. Use of the old order
will be supported in this release, but emit a ``DeprecationWarning``.
The legacy behavior will be dropped in a future release. (thanks to jaraco)
* :func:`distinct_permutations` was improved (thanks to jferard - see also `permutations with unique values <https://stackoverflow.com/questions/6284396/permutations-with-unique-values>`_ at StackOverflow.)
* An unused parameter was removed from :func:`substrings`. (thanks to pylang)
* Other changes:
* The docs for :func:`unique_everseen` were improved. (thanks to jferard and MSeifert04)
* Several Python 2-isms were removed. (thanks to jaraco, MSeifert04, and hugovk)
