Zope

==================

- Cleanups for Plone 5.2:

* in path alternatives, whitespace can now surround ``|``,

* non-ASCII in ``SubPathExpr`` now raises a ``CompilerError``
(instead of a ``UnicodeEncodeError``; to be compatible with
the ``chameleon`` template engine).

==================

- Fix problem with list comprehensions not working in Python 3. This was due
to the code not detecting variables used in side those expressions properly.

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

- Drop support for Python 2.7, 3.5, 3.6.

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

Bug fixes
+++++++++

- Pin ``AccessControl`` 4.2 for the `Manage WebDAV Locks` permission

- Fix ``HEAD`` requests on registered views
(`816 <https://github.com/zopefoundation/Zope/issues/816>`_)

- Improve ``chameleon`` --> ``zope.tales`` context wrapper
(support for template variable injection)
(`812 <https://github.com/zopefoundation/Zope/pull/812>`_).

- Require ``zope.tales>=5.0.2``

- Fix issue 717 by fully honoring the engine returned by
``PageTemplate.pt_getEngine``
(`717 <https://github.com/zopefoundation/Zope/issues/717>`_).
The engine also decides about the use of ``zope.tales``
(engine is an instance of ``zope.pagetemplate.engine.ZopeBaseEngine``)
or ``chameleon.tales`` (otherwise) TALES expressions.

- Fixed encoding issue of `displayname` WebDAV property
(`797 <https://github.com/zopefoundation/Zope/issues/797>`_)

- Fixed fallback implementation of ``manage_DAVget``
(`799 <https://github.com/zopefoundation/Zope/issues/799>`_)
