- 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 <https://pypi.python.org/pypi/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 #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 <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)
- Previous versions
- =================
- See :ref:`whats-old` for versions prior to v0.15.
