The Grok team is happy to announce the release of Grok 0.13!
This release is available on PyPI and a new index of specific versions
of packages used by this release has been frozen at
http://grok.zope.org/releaseinfo/grok-0.13.cfg. This means that new
projects created with grokproject will start using this release right
* New ``grok.traversable`` directive to make individual attributes
traversable without having to write a ``traverse`` method. Just give
it the attribute name and the attribute becomes traversable.
* ``grok.require`` now also accepts the permission class directly as
an argument, instead of just the permission name.
* The view ``url`` method has an optional parameter ``data``, which
is a dictionary with URL parameters to generate.
* New ``grok.OrderedContainer`` component.
* Easier test setup infrastructure in ``z3c.testsetup``, see `tests-
with-grok-testing`_ for more details.
* Improvements to viewlet support. ``Viewlet`` and ViewletManager``
templates now both receives a ``view`` namespace which is the view

``GlobalUtility``), their grokkers, as well as many of the basic
directives have been factored out to a reusable
* Ported directives to Martian's new directive implementation. As a
result, many helper functions that were available from ``grok.util``
were removed. The functionality is mostly available from the
directives themselves now.
* Refactored class grokkers to make use of Martian's new declarative
way for retrieving directive data from classes, and Martian's new
declarative way to write grokkers. See the `upgrade notes`_
(``doc/upgrade.txt``) for more information.
