5.3 (unreleased)

  • Nothing changed yet.

  • Add preliminary support for Python 3.13 as of 3.13a3.

5.1 (2023-10-05)

  • Add support for Python 3.12.

5.0.0 (2023-01-18)

  • Drop support for Python 2.7, 3.5, 3.6.

  • Remove proxying code for names that no longer exist in Python 3 like __long__ and some others. (#55)

4.6.1 (2022-11-16)

  • Add support for building arm64 wheels on macOS.

4.6.0 (2022-11-03)

  • Add support for Python 3.11.

4.5.1 (2022-09-15)

4.5.0 (2021-11-17)

  • Add support for Python 3.10.

4.4.0 (2021-07-22)

  • Add support for Python 3.9.

  • Create aarch64 wheels.

4.3.5 (2020-03-16)

  • Stop installing C header files on PyPy (which is what zope.proxy before 4.3.4 used to do), fixes issue 39.

4.3.4 (2020-03-13)

  • Fix a compilation warning on Python 3.8. The slot tp_print changed to tp_vectorcall_offset in 3.8 and must not be set. Prior to 3.8, it was reserved and ignored in all Python 3 versions. See issue 36.

  • Remove deprecated use of setuptools features. See issue 38.

4.3.3 (2019-11-11)

  • Add support for Python 3.8.

  • Drop support for Python 3.4.

4.3.2 (2019-07-12)

  • Fix error handling in ProxyBase.__setattr__: any the exception raised by PyString_AsString/PyUnicode_AsUTF8 would be silently swallowed up and ignored. See issue 31.

4.3.1 (2018-08-09)

  • Simplify the internal C handling of attribute names in __getattribute__ and __setattr__.

  • Make building the C extension optional. We still attempt to build it on supported platforms, but we allow it to fail in case of a missing compiler or headers. See issue 26.

  • Test the PURE_PYTHON environment and PyPy3 on Travis CI.

  • Add support for Python 3.7.

4.3.0 (2017-09-13)

  • Fix a potential rare crash when deallocating proxies. See issue 20.

  • Drop support for Python 3.3.

  • Drop support for “python test”.

  • 100% test coverage.

  • Fix indexing pure-Python proxies with slices under Python 3, and restore the use of __getslice__ (if implemented by the target’s type) under Python 2. Previously, pure-Python proxies would fail with an AttributeError when given a slice on Python 3, and on Python 2, a custom __getslice__ was ignored. See issue 21.

4.2.1 (2017-04-23)

  • Make the pure-Python implementation of sameProxiedObjects handle proxies. See issue 15.

  • Add support for Python 3.6.

4.2.0 (2016-05-05)

  • Correctly strip proxies in removeAllProxies. See issue 13.

  • Avoid poisoning the user’s global wheel cache when testing PURE_PYTHON environments under tox,

  • Drop support for Python 2.6 and 3.2.

  • Add support for Python 3.5.

4.1.6 (2015-06-02)

  • Make subclasses of ProxyBase properly delegate __module__ to the wrapped object. This fixes some zope.interface lookups under PyPy.

  • Make the pure-Python implementation of ProxyBase properly report the zope.interface interfaces implemented by builtin types like list. This fixes some zope.interface lookups under PyPy.

4.1.5 (2015-05-19)

  • Make the C implementation proxy __unicode__ correctly.

  • Make the C implementation use the standard methods to proxy int and float.

  • Make the pure Python implementation handle descriptors defined in subclasses like the C version. See

4.1.4 (2014-03-19)

  • Add support for Python 3.4.

  • Update to version 2.2.

4.1.3 (2013-03-12)

  • Fix interface object introspection in PyPy. For some reason PyPy makes attributes available despite the restrictive __slots__ declaration.

  • Add a bunch of tests surrounding interface lookup and adaptation.

4.1.2 (2013-03-11)

  • Make PyProxyBase.__iter__() return the result of PyProxyBase._wrapped.__iter__ if available, otherwise falling back to Python internals. The previous implementation always created a generator.

  • In PyProxyBase.__setattr__(), allow setting of properties on the proxy itself. This is needed to properly allow proxy extensions as was evidenced int he module.

4.1.1 (2012-12-31)

  • Fleshed out PyPI Trove classifiers.

4.1.0 (2012-12-19)

  • Enable compilation of dependent modules under Py3k.

  • Replace use of PyCObject APIs with equivalent PyCapsule APIs, except under Python 2.6.

    N.B. This change is an ABI incompatibility under Python 2.7:

    extensions built under Python 2.7 against 4.0.x versions of zope.proxy must be rebuilt.

4.0.1 (2012-11-21)

  • Add support for Python 3.3.

4.0.0 (2012-06-06)

  • Add support for PyPy.

    N.B.: the C extension is not built under PyPy.

  • Add a pure-Python reference / fallback implementations of zope.proxy.ProxyBase and the proxy module API functions.

    N.B.: the pure-Python proxy implements all regular features of ProxyBase; however, it does not exclude access to the wrapped object in the same way that the C version does. If you need that information hiding (e.g., to implement security sandboxing), you still need to use the C version.

  • Add support for continuous integration using tox and jenkins.

  • 100% unit test coverage.

  • Add Sphinx documentation: moved doctest examples to API reference.

  • Add ‘ docs’ alias (installs Sphinx and dependencies).

  • Add ‘ dev’ alias (runs develop plus installs nose and coverage).

  • Replace deprecated zope.interface.implements usage with equivalent zope.interface.implementer decorator.

  • Drop support for Python 2.4 and 2.5.

  • Add Python 3.2 support.

3.6.1 (2010-07-06)

  • Make tests compatible with Python 2.7.

3.6.0 (2010-04-30)

  • Remove test extra and the remaining dependency on zope.testing.

  • Remove use of ‘zope.testing.doctestunit’ in favor of stdlib’s ‘doctest.

3.5.0 (2009/01/31)

  • Add support to bootstrap on Jython.

  • Use zope.container instead of

3.4.2 (2008/07/27)

  • Make C code compatible with Python 2.5 on 64bit architectures.

3.4.1 (2008/06/24)

  • Bug: Update script to conform to common layout. Also updated some of the fields.

  • Bug: Honor pre-cooked indices for tuples and lists in the __getslice__() and __setslice__() methods. See

3.4.0 (2007/07/12)

  • Feature: Add a decorator module that supports declaring interfaces on proxies that get blended with the interfaces of the things they proxy.

3.3.0 (2006/12/20)

  • Corresponds to the verison of the zope.proxy package shipped as part of the Zope 3.3.0 release.

3.2.0 (2006/01/05)

  • Corresponds to the verison of the zope.proxy package shipped as part of the Zope 3.2.0 release.

3.0.0 (2004/11/07)

  • Corresponds to the verison of the zope.proxy package shipped as part of the Zope X3.0.0 release.
