====================================================
ExtensionClass and ExtensionClass-related packages
====================================================
ExtensionClass
==============
This package provides a metaclass that allows classes implemented in
extension modules to be subclassed in Python. Unless you need
ExtensionClasses for legacy applications (e.g. Zope), you probably
want to use Python's new-style classes (available since Python 2.2).
ComputedAttribute
=================
This package provides a way to attach attributes to an
``ExtensionClass`` or instance that are computed by calling a
callable. This works very much like ``property`` known from new-style
classes, except that a ``ComputedAttribute`` can also be attached to
an instance and that it honours ExtensionClass semantics (which is
useful for retaining Acquisition wrappers, for example).
MethodObject
============
This package lets you attach additional "methods" to ExtensionClasses.
These "methods" are actually implemented by subclassing the
``MethodObject.Method`` class and implementing the ``__call__`` method
there. Instances of those classes will be bound to the instances
they're attached to and will receive that instance object as a first
parameter (after ``self``).

Changelog
===========
4.7 (2022-09-16)
================
- Update Python 3.11 support to rc2.
- Disable unsafe math optimizations in C code.
(`#55 <https://github.com/zopefoundation/ExtensionClass/pull/55>`_)
4.6 (2022-01-14)
================
- Add support for Python 3.10 and 3.11 (as of alpha 3).
4.5.1 (2021-06-11)
==================
- Create wheels for Linux (2010, 2014 and aarch) and MacOS.
4.5.0 (2020-10-07)
==================
- Drop support for Python 3.4.
- Add support for Python 3.8 and 3.9.
- Fix accessing ``__parent__`` when it is defined as a class attribute
that is ``None`` (e.g., in subclasses of
``zope.conatiner.contained.Contained``). See `issue 24
<https://github.com/zopefoundation/ExtensionClass/issues/24>`_.
4.4.0 (2018-10-05)
==================
- Fail if C extensions couldn't be compiled on compatible platforms.
- Add Appveyor configuration to automate building Windows eggs
- Add support for Python 3.7.
- Fix getting attributes that are data descriptors in the Python
implementation.
- Reach and automatically maintain 100% test coverage.
4.3.0 (2017-02-22)
==================
- Drop support for Python 3.3.
- Remove unused C macro from ``ExtensionClass.h``.
- Fix C compilation under Windows.
4.2.1 (2017-02-02)
==================
- Fix problems with computed attribute and property wrapping.
4.2.0 (2017-01-18)
==================
- Port the C extension to Python 3.
- Add support for Python 3.5 and 3.6.
- Drop support for Python 2.6, 3.2.
4.1.2 (2015-04-03)
==================
- Fix calling of ``__class_init__`` hook by Python implementation.
4.1.1 (2015-03-20)
==================
- Avoid wrapping ``__parent__`` in pure-Python version. Matches
change made to C version in afb8488. See issue #3.
4.1 (2014-12-18)
================
- Housekeeping changes only.
4.1b1 (2014-11-12)
==================
- Added compatibility with Python 3.4.
4.1a1 (2013-05-04)
==================
- Added compatibility with Python 3.2 and 3.3 using the Python reference
implementation.
- Add Python reference implementation. Used by default on PyPy.
4.0 (2013-02-24)
================
- Added trove classifiers to project metadata.
4.0a1 (2011-12-13)
==================
- Don't create wrappers when retrieving parent pointers.
2.13.2 (2010-06-16)
===================
- LP #587760: Handle tp_basicsize correctly.
2.13.1 (2010-04-03)
===================
- Removed undeclared testing dependency on zope.testing.
- Removed cruft in ``pickle/pickle.c`` related to removed ``__getnewargs__``.
2.13.0 (2010-02-22)
===================
- Avoid defining ``__getnewargs__`` as not to defeat the ZODB persistent
reference optimization. Refs https://bugs.launchpad.net/zope2/+bug/143657.
In order to take advantage of this optimization, you need to re-save your
objects.
2.12.0 (2010-02-14)
===================
- Removed old build artifacts and some metadata cleanup.
- Added support for method cache in ExtensionClass. Patch contributed by
Yoshinori K. Okuji. See https://bugs.launchpad.net/zope2/+bug/486182.
2.11.3 (2009-08-02)
===================
- Further 64-bit fixes (Python 2.4 compatibility).
2.11.2 (2009-08-02)
===================
- Fixed 64-bit compatibility issues for Python 2.5.x / 2.6.x. See
http://www.python.org/dev/peps/pep-0353/ for details.
2.11.1 (2009-02-19)
===================
- Initial egg release.
