Z3c.ptcompat

----------------

- Added support for Python 3.4, 3.5, PyPy and PyPy3.

- Dropped support for Python 2.6.

--------------------

- Added support for Python 3.3.

- Ensured that ``chameleon.tal.ReapeatDict`` can be adapted. (Needs to be
fixed in Chameleon.)

- Replaced deprecated ``zope.interface.implements`` usage with equivalent
``zope.interface.implementer`` decorator.

- Dropped support for Python 2.4 and 2.5.

------------------

- Move ``zope.testing`` to test dependencies, add undeclared dependencies.

----------------

- Update implementation to use component-based template engine
configuration, plugging directly into the Zope Toolkit framework.

The package no longer provides template classes, or ZCML directives;
you should import directly from the ZTK codebase.

Also, note that the ``PREFER_Z3C_PT`` environment option has been
rendered obsolete; instead, this is now managed via component
configuration.

- Upgrade to Chameleon 2.x.

------------------

- Added not yet declared test dependency on ``zope.testing``.

- Fixed test tear down so tests can be run multiple times.

------------------

- Remove broken templates from registry during engine migration. In
some testing situation, stale templates would be tracked in the
regsitry.

- Existing template instances are now migrated to the right engine
when using the ``enable`` and ``disable`` methods. [malthe]
