Wagtail is now compatible with Django 1.10. Thanks to Mikalai Radchuk and Paul J Stevens for developing this, and to Tim Graham for reviewing and additional Django core assistance.
In previous releases, the standard way of rendering the HTML content of a StreamField was through a simple variable template tag, such as ``{{ page.body }}``. This had the drawback that any templates used in the StreamField rendering would not inherit variables from the parent template's context, such as ``page`` and ``request``. To address this, a new template tag ``{% include_block page.body %}`` has been introduced as the new recommended way of outputting Streamfield content - this replicates the behaviour of Django's ``{% include %}`` tag, passing on the full template context by default. For full documentation, see :ref:`streamfield_template_rendering`. This feature was developed by Matt Westcott, and additionally ported to Jinja2 (see: :doc:`/advanced_topics/jinja2`) by Mikalai Radchuk.
* Multiple ChooserBlocks inside a StreamField are now prefetched in bulk, for improved performance (Michael van Tellingen, Roel Bruggink, Matt Westcott)
* Added formal APIs for customising the display of StructBlock forms within the page editor - see :ref:`custom_editing_interfaces_for_structblock` (Matt Westcott)
* Added ability to delete users through Settings -> Users (Vincent Audebert; thanks also to Ludolf Takens and Tobias Schmidt for alternative implementations)
* Page previews now pass additional HTTP headers, to simulate the page being viewed by the logged-in user and avoid clashes with middleware (Robert Rollins)
The ``choices`` field on the ``wagtailforms.models.AbstractFormField`` model has been changed from a ``CharField`` to a ``TextField``, to allow it to be of unlimited length. If you are using the ``wagtailforms`` module in your project, you will need to run ``python manage.py makemigrations`` and ``python manage.py migrate`` after upgrading, in order to apply this change to your form page models.
The mixin class ``wagtail.wagtailadmin.taggable.TagSearchable``, used internally by image and document models, has been deprecated. If you are using custom image or document models in your project, the migration(s) which created them will contain frozen references to ``wagtail.wagtailadmin.taggable.TagSearchable``, which must now be removed. The line:
The ``render`` and ``render_basic`` methods on ``wagtail.wagtailcore.blocks.Block`` have been updated to accept an optional ``context`` keyword argument, a template context to use when rendering the block. If you have defined any custom StreamField blocks that override either of these methods, the method signature now needs to be updated to include this keyword argument:
