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

* Support setting ``SHOP_PRODUCT_SORT_OPTIONS`` = (). - If empty, sort category pages by the current default ``'-date_added'`` by. default. - If empty, don't display the product sorting form - ryneeverett
* Use dict for context. Fix invoices in ``django-1.10``. The invoice view raises a TypeError in ``django-1.10``. The following lines. in the release notes explain the change: > - Django template objects returned by ``get_template()`` and. > ``select_template()`` no longer accept a Context in their render() method. > - Template response APIs enforce the use of dict and backend-dependent. > template objects instead of Context and Template respectively - ryneeverett
* Purge ``SHOP_USE_PRODUCT_TYPES`` settings. As AlexHill pointed out, it's risky, complex, and not useful - ryneeverett
* Use new ``ContentTyped.set_content_model`` method - ryneeverett
* Update ``project_template`` media library setting. See. ``https://github.com/ryneeverett/mezzanine/commit/7370cb2854fdbc2f45d7533a02218bf49cff619f`` - ryneeverett

* Fix "Resend Order Email" button on complete view. It currently 404's because the user isn't logged in. Surely I'm missing. something here. Both the `login_required` decorator and the button on. the completion page were present in the initial commit of this view - ryneeverett
* Remove usages of deprecated ``settings.use_editable``. I removed the instance in `default_tax_handler` because it doesn't seem. to serve any purpose. In every other instance I switched to `settings.clear_cache`. I don't. know if this is actually necessary in every case but caution suggests. not changing things one doesn't understand - ryneeverett

Note that unlike `Page`, uncustomized `Product`'s are still. valid. - Switch from adminmedia to staticfiles. - The first template found in the list gets rendered, so we need to. prepend the optional custom product template - ryneeverett
