Compatibility
-------------

Oscar 1.6 is compatible with Django 1.11 and Django 2.0 as well as Python 2.7, 3.4,
3.5 and 3.6.

Official support for Django 1.8, 1.9 and 1.10 has been dropped.

.. _new_in_1.6:

What's new in Oscar 1.6?
------------------------
 - Added support for managing large amounts of vouchers grouped in sets.

Removal of deprecated features
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

 - ``oscar.core.phonenumber.PhoneNumber`` is removed.
   Use ``phonenumber_field.phonenumber.PhoneNumber`` instead.

 - Removed the redundant ``OSCAR_PROMOTION_MERCHANDISING_BLOCK_TYPES`` setting.

Minor changes
~~~~~~~~~~~~~
 - The majority of the Oscar class imports now use dynamic loading, instead of
   direct imports, for better extensibility and customisability.

 - Added the ability to specify a custom class loader through the
   ``OSCAR_DYNAMIC_CLASS_LOADER`` setting.

 - Customer transaction emails were reworked to use Mailgun templates, so that
   they have a more modern appearance.

 - ``SearchHandler.get_search_form`` method now accepts additional
   keyword arguments, which will be passed on search form class instance.

 - Added ``get_stock_info`` hook to ``oscar.apps.basket.models.Basket``  for
   implementing strategies that depend on product options.

 - Fixed the page create/update views in the dashboard to correctly validate
   URLs. Invalid characters in URLs will raise a validation error, as will
   URLs longer than 100 characters.

 - The default shipping method
   ( ``oscar.apps.basket.views.BasketView.get_default_shipping_address``)
   on the basket summary page now uses the user's default shipping address to
   calculate an indicative shipping cost.

 - Fixed ``ExtendedURLValidator`` for locale-prefixed URLs for locales, different
   from current (see :issue:`1481`). Previously, validation did not pass when
   if the current locale was ``en-gb`` and, the a visited URL was ``/de/catalogue/``
   and visa versa due to Django's default behaviour.

 - Product attribute value save is now handled by separate methods, to make it
     easier to override this behaviour.

 - Address hash generation is now separated from the summary in order to
   preserve same behaviour when summary property customised (see :issue:`1537`).
   They can use different field names, listed out in `base_fields` and
   `hash_fields` respectively. Also hash generation now became
   platform-independent and generates the same for Python 2 and 3.
   Corresponding data migration will update hashes automatically. Take it into
   account that it will take time to run if you have large user base.

 - Compact basket form is no longer displayed for the products with options
   on product list pages since it caused form elements to impose inside the
   product box (see :issues:`1976`).

- Added ``has_options`` property to the
  ``oscar.apps.catalogue.models.Product`` model to indicate whether an
  instance or its product class has product options.

 - ``oscar.core.validators.validate_password`` was removed.
   Use ``django.contrib.auth.password_validation.validate_password`` instead.

 - ``oscar.core.validators.CommonPasswordValidator`` was removed. Use ``django.contrib.auth.password_validation.CommonPasswordValidator`` instead.

 - User notifications are marked as read only when viewed in detail, instead of
   being marked as read in bulk when the notification list was viewed.

 - Oscar's ``ImageInput``, ``TimePickerInput``, ``DatePickerInput`` and
   ``DateTimePickerInput`` all use templates for rendering.

 - It is now possible to manage images for variant products and their parents.

 - For variant products we now display their own images on product detail page
   and fallback to parent product images if they don't have any.

 - Basket line form quantity field now has "max" attribute with the maximum
   allowed quantity in it based on product availability and basket threshold
   (see :issue:`1412`).

 - An unused setting ``OSCAR_SETTINGS`` was removed from ``oscar.core.defaults``.

 - Fixed ``PhoneNumberMixin``s handling of empty phone number fields in forms.

.. _incompatible_in_1.6:

Backwards incompatible changes in Oscar 1.6
-------------------------------------------

 - Fixed a regression introduced in Oscar 1.5 (see :issue:`2664`) where
   ``StockRequired.availability_policy`` was dependent on the product
   having a price. Price and availability are now decoupled, and it is possible
   to defer determination of a price until a product is added to the basket.

 - ``oscar.apps.customer.auth_backends.EmailBackend`` now rejects inactive users
   (where ``User.is_active`` is ``False``).

 - ``EmailBackend`` no longer enforces its own password strength validation,
   and relies instead on the ``AUTH_PASSWORD_VALIDATORS`` setting used by Django.

 - ``oscar.apps.basket.middleware.BasketMiddleware`` was rewritten as new-style
   middleware for Django 1.11.

 - ``oscar.apps.offer.models.ConditionalOffer`` now has a new flag
   ``exclusive`` to denote that the offer involved can not be combined on the
   same item on the same basket line with another offer.
   This flag is used by ``oscar.apps.basket.utils.LineOfferConsumer``, a facade
   that supersedes the old ``oscar.apps.basket.models.Line._affected_items`` counter,
   and replaces it with a more fine-grained approach. This makes it possible to apply
   two distinct non-exclusive offers on the same line items, for example
   multiple distinct vouchers.
   A couple of methods on the ``Line`` model have been extended with an
   optional ``offer`` argument, i.e. ``discount`` and ``consume``, so if you
   are using a customised ``Line`` model, you have to update your methods'
   signatures.

 - Invalid URL names supplied to the ``OSCAR_DASHBOARD_NAVIGATION`` setting
   are now logged as an exception (previously they were silently ignored).
   The offending menu item will be skipped during menu rendering.
   In Oscar 1.8 the exception will be raised without being intercepted.

 - All signals are now loaded directly rather than using dynamic imports.

 - Stock manipulation (allocation/consumption/cancellation) now only happens if
   the ``track_stock`` property of the product's class is set to true.

 - ``oscar.forms.widgets.RemoteSelect`` was updated to work with version 4 of
   select2. Instead of rendering a hidden input it now renders a normal
   ``select`` element.

 - The :py:mod:`django-extra-views` dependency was upgraded to version 0.11, and the
   basket views that rely on ``extra_views.ModelFormSetView`` updated to use the
   new factory_kwargs attribute.

 - jQuery UI was removed from Oscar's static files. Projects that require it
   should install it at the project level.

 - Compatibility for Internet Explorer version 9 an lower was dropped from Oscar's
   templates and styles.

 - The Google Analytics tracking code provided by Oscar now uses ``gtag.js`` API
   instead of the deprecated ``analytics.js``. Analytics are also disabled by
   default in Oscar's dashboard.

Dependency changes
------------------

- Upgraded ``jquery`` to version 3.3.1.

- Upgraded ``bootstrap`` to version 3.3.7.

- Upgraded ``bootstrap-datetimepicker`` to v2.4.4.

- Upgraded ``jquery-mousewheel`` to v3.1.13.

- Upgraded ``inputmask`` to v3.2.7.

- Upgraded ``jquery-sortable`` to v0.9.13.

- Upgraded ``select2`` to v4.0.5.
