Changes

7.0 (2025-09-12)

• Replace pkg_resources namespace with PEP 420 native namespace.

6.1 (2025-02-14)

• Add support for Python 3.12, 3.13.

• Add support for Python 3.11.

• Make the tests compatible with zope.testing >= 5.

5.0.0 (2022-03-25)

• Remove __cmp__ methods. Since the implementation of the rich comparison methods (__eq__, etc) in 4.0a1, the interpreter won’t call __cmp__, even on Python 2. See issue 10.

4.2.0 (2018-10-26)

• Drop support for Python 2.6 and 3.3.

4.1.0 (2014-12-27)

• Add support for PyPy (PyPy3 blocked on PyPy3-compatible zodbpickle).

• Add support for Python 3.4.

4.0.0 (2014-12-20)

• Add support for testing on Travis.

4.0.0a2 (2013-02-25)

• Ensure that the SimpleKeyReference implementation (used for testing) also implements rich comparison properly.

4.0.0a1 (2013-02-22)

• Add support for Python 3.3.

• Replace deprecated zope.component.adapts usage with equivalent zope.component.adapter decorator.

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

• Drop support for Python 2.4 and 2.5.

3.6.4 (2011-11-30)

• Fix tests broken by removal of zope.testing from test dependencies: avoid the ZODB3 module that needs it.

3.6.3 (2011-11-29)

• Prefer the standard libraries doctest module to the one from zope.testing.

3.6.2 (2009-09-15)

• Make the tests pass with ZODB3.9, which changed the repr() of the persistent classes.

3.6.1 (2009-02-01)

• Load keyreferences, pickled by old zope.app.keyreference even if its not installed anymore (so don’t break if one updates a project that don’t directly depends on zope.app.keyreference).

3.6.0 (2009-01-31)

• Rename zope.app.keyreference to zope.keyreference.
