What's new 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)
|
|
|
|
|
|
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)
