Changes in version 0.16.0 (2016-10-27)

This release removes the ``configparser`` package as an alias for

``ConfigParser`` on Py2 to improve compatibility with the backported

`configparser package <https://pypi.org/project/configparser/>`. Previously

``python-future`` and the PyPI ``configparser`` backport clashed, causing

various compatibility issues. (Issues #118, #181)

If your code previously relied on ``configparser`` being supplied by

``python-future``, the recommended upgrade path is to run ``pip install

configparser`` or add ``configparser`` to your ``requirements.txt`` file.

Note that, if you are upgrading ``future`` with ``pip``, you may need to

uninstall the old version of future or manually remove the

``site-packages/future-0.15.2-py2.7.egg`` folder for this change to take

effect on your system.

This releases also fixes these bugs:

- Fix ``newbytes`` constructor bug. (Issue #171)

- Fix semantics of ``bool()`` with ``newobject``. (Issue #211)

- Fix ``standard_library.install_aliases()`` on PyPy. (Issue #205)

- Fix assertRaises for ``pow`` and ``compile``` on Python 3.5. (Issue #183)

- Fix return argument of ``future.utils.ensure_new_type`` if conversion to

new type does not exist. (Issue #185)

- Add missing ``cmp_to_key`` for Py2.6. (Issue #189)

- Allow the ``old_div`` fixer to be disabled. (Issue #190)

- Improve compatibility with Google App Engine. (Issue #231)

- Add some missing imports to the ``tkinter`` and ``tkinter.filedialog``

package namespaces. (Issues #212 and #233)

- More complete implementation of ``raise_from`` on PY3. (Issues #141,

#213 and #235, fix provided by Varriount)

Changes in version 0.15.2 (2015-09-11)

This is a minor bug-fix release:

- Fix ``socket.create_connection()`` backport on Py2.6 (issue #162)

- Add more tests of ``urllib.request`` etc.

- Fix ``newsuper()`` calls from the ``__init__`` method of PyQt subclassses

(issue #160, thanks to Christopher Arndt)

Changes in version 0.15.1 (2015-09-09)

This is a minor bug-fix release:

- Use 3-argument ``socket.create_connection()`` backport to restore Py2.6

compatibility in ``urllib.request.urlopen()`` (issue #162)

- Remove breakpoint in ``future.backports.http.client`` triggered on certain

data (issue #164)

- Move ``exec`` fixer to stage 1 of ``futurize`` because the forward-compatible ``exec(a, b)``

idiom is supported in Python 2.6 and 2.7. See

https://docs.python.org/2/reference/simple_stmts.html#exec.

Changes in version 0.15.0 (2015-07-25)

This release fixes compatibility bugs with CherryPy's Py2/3 compat layer and

the latest version of the ``urllib3`` package. It also adds some additional

backports for Py2.6 and Py2.7 from Py3.4's standard library.

New features:

- ``install_aliases()`` now exposes full backports of the Py3 urllib submodules

(``parse``, ``request`` etc.) from ``future.backports.urllib`` as submodules

of ``urllib`` on Py2. This implies, for example, that

``urllib.parse.unquote`` now takes an optional encoding argument as it does

on Py3. This improves compatibility with CherryPy's Py2/3 compat layer (issue

#158).

- ``tkinter.ttk`` support (issue #151)

- Backport of ``collections.ChainMap`` (issue #150)

- Backport of ``itertools.count`` for Py2.6 (issue #152)

- Enable and document support for the ``surrogateescape`` error handler for ``newstr`` and ``newbytes`` objects on Py2.x (issue #116). This feature is currently in alpha.

- Add constants to ``http.client`` such as ``HTTP_PORT`` and ``BAD_REQUEST`` (issue #137)

- Backport of ``reprlib.recursive_repr`` to Py2

Bug fixes:

- Add ``HTTPMessage`` to ``http.client``, which is missing from ``httplib.__all__`` on Python <= 2.7.10. This restores compatibility with the latest ``urllib3`` package (issue #159, thanks to Waldemar Kornewald)

- Expand newint.__divmod__ and newint.__rdivmod__ to fall back to <type 'long'>

implementations where appropriate (issue #146 - thanks to Matt Bogosian)

- Fix newrange slicing for some slice/range combos (issue #132, thanks to Brad Walker)

- Small doc fixes (thanks to Michael Joseph and Tim Tröndle)

- Improve robustness of test suite against opening .pyc files as text on Py2

- Update backports of ``Counter`` and ``OrderedDict`` to use the newer

implementations from Py3.4. This fixes ``.copy()`` preserving subclasses etc.

- ``futurize`` no longer breaks working Py2 code by changing ``basestring`` to

``str``. Instead it imports the ``basestring`` forward-port from

``past.builtins`` (issues #127 and #156)

- ``future.utils``: add ``string_types`` etc. and update docs (issue #126)
