.. _whats-new: What's New ********** .. _whats-new-0.16.x: What's new in version 0.16.0 (2016-09-22) ========================================== This release removes the ``configparser`` package as an alias for ``ConfigParser`` on Py2 to improve compatibility with the backported `configparser package `. 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 #163) - 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) - Fix ``raise_from`` on PY3 when the exception cannot be recreated from its repr. (Issues #213 and #235, fix provided by Varriount) What's new 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) What's new 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. What's new 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 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) Previous versions ================= See :ref:`whats-old` for versions prior to v0.15.
