zope.annotation 4.4.1

Converted doctests to Sphinx documentation. Doctest snippets are still tested via tox -e docs.

LP #98462: add additional “iterable mapping” methods to IAnnotations.

LP #878265:

• Make persistent (used only for doctests) a soft dependency, installable via the zope.annotation[btree] extra.

• Make BTrees (used for attribute storage) a soft dependency, installable via the zope.annotation[btree] extra. Fall back to using dict for attribute storage if BTrees is not importable.

Add support for Python 3.4.

Don’t make AttributeAnnotations available as a view.

Add __bool__ method to IAnnotations API for Python 3 compatibility.

Add tox.ini.

Add support for Python 3.3 and PyPy.

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.

Include zcml dependencies in configure.zcml, require the necessary packages via a zcml extra, added tests for zcml.

Add ZODB3 to install_requires, because it’s a true requirement of this package, not just a testing requirement, as BTrees are in use.

Fix one test that was inactive because it’s function was overriden by a mistake.

Clean up package description and documentation a bit.

Change mailing list address to zope-dev at zope.org, as zope3-dev at zope.org is now retired.

Remove old zpkg-related files.

Annotation factories take care not to store proxies in the database, so adapting an object wrapped in a LocationProxy works correctly. Fixes https://bugs.launchpad.net/zope3/+bug/261620

Annotation factories are no longer containing the factored object. Instead the objects are located using zope.location. This removes a dependency to zope.app.container.
