1.7¶

See the Django 1.5 release notes for more
details on these changes.

  • The module django.utils.simplejson will be removed. The standard library
    provides json which should be used instead.

    builtin version should be used instead.
  • Auto-correction of INSTALLED_APPS and TEMPLATE_DIRS settings when they are
    specified as a plain string instead of a tuple will be removed and raise an
    exception.
  • The mimetype argument to the __init__ methods of
    HttpResponse,
    SimpleTemplateResponse, and
    TemplateResponse, will be removed.
    content_type should be used instead. This also applies to the
    render_to_response() shortcut and the sitemap views,
    index() and
    sitemap().
  • When HttpResponse is instantiated with an iterator,
    or when content is set to an iterator,
    that iterator will be immediately consumed.
  • The AUTH_PROFILE_MODULE setting, and the get_profile() method on
    the User model, will be removed.

    available starting with Python 2.6 instead.
  • The undocumented check_for_test_cookie method in
    AuthenticationForm will be removed
    following an accelerated deprecation. Users subclassing this form should
    remove calls to this method, and instead ensure that their auth related views
    are CSRF protected, which ensures that cookies are enabled.

    supports base36 encoded user IDs
    (django.contrib.auth.views.password_reset_confirm_uidb36) will be
    removed. If your site has been running Django 1.6 for more than
    PASSWORD_RESET_TIMEOUT_DAYS, this change will have no effect. If
    not, then any password reset links generated before you upgrade to Django 1.7
    won’t work after the upgrade.
  • The django.utils.encoding.StrAndUnicode mix-in will be removed.
    Define a __str__ method and apply the
    python_2_unicode_compatible() decorator instead.

    django.utils.itercompat.all and django.utils.itercompat.any will
    be removed. The Python builtin versions should be used instead.
  • The csrf_response_exempt and csrf_view_exempt decorators will
    be removed. Since 1.4 csrf_response_exempt has been a no-op (it
    returns the same function), and csrf_view_exempt has been a
    synonym for django.views.decorators.csrf.csrf_exempt, which should
    be used to replace it.
  • The django.core.cache.backends.memcached.CacheClass backend
    was split into two in Django 1.3 in order to introduce support for
    PyLibMC. The historical CacheClass will be removed in favor of
    django.core.cache.backends.memcached.MemcachedCache.

    be accessible through their GB-prefixed names (GB is the correct
    ISO 3166 code for United Kingdom).

    django.contrib.gis.geoip in 1.4 — the shortcut in
    django.contrib.gis.utils will be removed.

    include(), patterns(), and url(), plus
    handler404 and handler500
    are now available through django.conf.urls.

    from django.core.management. This also means that the old (pre-1.4)
    style of manage.py file will no longer work.
  • Setting the is_safe and needs_autoescape flags as attributes of
    template filter functions will no longer be supported.
  • The attribute HttpRequest.raw_post_data was renamed to HttpRequest.body
    in 1.4. The backward compatibility will be removed —
    HttpRequest.raw_post_data will no longer work.
  • The value for the post_url_continue parameter in
    ModelAdmin.response_add() will have to be either None (to redirect
    to the newly created object’s edit page) or a pre-formatted url. String
    formats, such as the previous default '../%s/', will not be accepted any
    more.

1.5¶

See the Django 1.3 release notes for more
details on these changes.

  • Starting Django without a SECRET_KEY will result in an exception
    rather than a DeprecationWarning. (This is accelerated from the usual
    deprecation path; see the Django 1.4 release notes.)
  • The mod_python request handler will be removed. The mod_wsgi
    handler should be used instead.
  • The template attribute on django.test.client.Response
    objects returned by the test client will be removed.
    The templates attribute should be
    used instead.
  • The django.test.simple.DjangoTestRunner will be removed.
    Instead use a unittest-native class. The features of the
    django.test.simple.DjangoTestRunner (including fail-fast and
    Ctrl-C test termination) can currently be provided by the unittest-native
    TextTestRunner.
  • The undocumented function
    django.contrib.formtools.utils.security_hash will be removed,
    instead use django.contrib.formtools.utils.form_hmac
  • The function-based generic view modules will be removed in favor of their
    class-based equivalents, outlined here.
  • The django.core.servers.basehttp.AdminMediaHandler will be
    removed. In its place use
    django.contrib.staticfiles.handlers.StaticFilesHandler.
  • The template tags library adminmedia and the template tag {%
    admin_media_prefix %}
    will be removed in favor of the generic static files
    handling. (This is faster than the usual deprecation path; see the
    Django 1.4 release notes.)
  • The url and ssi template tags will be modified so that the first
    argument to each tag is a template variable, not an implied string. In 1.4,
    this behavior is provided by a version of the tag in the future template
    tag library.
  • The reset and sqlreset management commands will be removed.
  • Authentication backends will need to support an inactive user
    being passed to all methods dealing with permissions.
    The supports_inactive_user attribute will no longer be checked
    and can be removed from custom backends.
  • transform() will raise
    a GEOSException when called
    on a geometry with no SRID value.
  • django.http.CompatCookie will be removed in favor of
    django.http.SimpleCookie.
  • django.core.context_processors.PermWrapper and
    django.core.context_processors.PermLookupDict will be removed in
    favor of the corresponding
    django.contrib.auth.context_processors.PermWrapper and
    django.contrib.auth.context_processors.PermLookupDict, respectively.
  • The MEDIA_URL or STATIC_URL settings will be
    required to end with a trailing slash to ensure there is a consistent
    way to combine paths in templates.
  • django.db.models.fields.URLField.verify_exists will be removed. The
    feature was deprecated in 1.3.1 due to intractable security and
    performance issues and will follow a slightly accelerated deprecation
    timeframe.
  • Translations located under the so-called project path will be ignored during
    the translation building process performed at runtime. The
    LOCALE_PATHS setting can be used for the same task by including the
    filesystem path to a locale directory containing non-app-specific
    translations in its value.
  • The Markup contrib app will no longer support versions of Python-Markdown
    library earlier than 2.1. An accelerated timeline was used as this was
    a security related deprecation.
  • The CACHE_BACKEND setting will be removed. The cache backend(s) should be
    specified in the CACHES setting.

1.4¶

See the Django 1.2 release notes for more
details on these changes.

  • CsrfResponseMiddleware and CsrfMiddleware will be removed. Use
    the {% csrf_token %} template tag inside forms to enable CSRF
    protection. CsrfViewMiddleware remains and is enabled by default.
  • The old imports for CSRF functionality (django.contrib.csrf.*),
    which moved to core in 1.2, will be removed.
  • The django.contrib.gis.db.backend module will be removed in favor
    of the specific backends.
  • SMTPConnection will be removed in favor of a generic Email backend API.
  • The many to many SQL generation functions on the database backends
    will be removed.
  • The ability to use the DATABASE_* family of top-level settings to
    define database connections will be removed.
  • The ability to use shorthand notation to specify a database backend
    (i.e., sqlite3 instead of django.db.backends.sqlite3) will be
    removed.
  • The get_db_prep_save, get_db_prep_value and
    get_db_prep_lookup methods will have to support multiple databases.
  • The Message model (in django.contrib.auth), its related
    manager in the User model (user.message_set), and the
    associated methods (user.message_set.create() and
    user.get_and_delete_messages()), will be removed. The
    messages framework should be used
    instead. The related messages variable returned by the
    auth context processor will also be removed. Note that this
    means that the admin application will depend on the messages
    context processor.
  • Authentication backends will need to support the obj parameter for
    permission checking. The supports_object_permissions attribute
    will no longer be checked and can be removed from custom backends.
  • Authentication backends will need to support the AnonymousUser class
    being passed to all methods dealing with permissions. The
    supports_anonymous_user variable will no longer be checked and can be
    removed from custom backends.
  • The ability to specify a callable template loader rather than a
    Loader class will be removed, as will the load_template_source
    functions that are included with the built in template loaders for
    backwards compatibility.
  • django.utils.translation.get_date_formats() and
    django.utils.translation.get_partial_date_formats(). These functions
    will be removed; use the locale-aware
    django.utils.formats.get_format() to get the appropriate formats.
  • In django.forms.fields, the constants: DEFAULT_DATE_INPUT_FORMATS,
    DEFAULT_TIME_INPUT_FORMATS and
    DEFAULT_DATETIME_INPUT_FORMATS will be removed. Use
    django.utils.formats.get_format() to get the appropriate
    formats.
  • The ability to use a function-based test runner will be removed,
    along with the django.test.simple.run_tests() test runner.
  • The views.feed() view and feeds.Feed class in
    django.contrib.syndication will be removed. The class-based view
    views.Feed should be used instead.
  • django.core.context_processors.auth. This release will
    remove the old method in favor of the new method in
    django.contrib.auth.context_processors.auth.
  • The postgresql database backend will be removed, use the
    postgresql_psycopg2 backend instead.
  • The no language code will be removed and has been replaced by the
    nb language code.
  • Authentication backends will need to define the boolean attribute
    supports_inactive_user until version 1.5 when it will be assumed that
    all backends will handle inactive users.
  • django.db.models.fields.XMLField will be removed. This was
    deprecated as part of the 1.3 release. An accelerated deprecation
    schedule has been used because the field hasn’t performed any role
    beyond that of a simple TextField since the removal of oldforms.
    All uses of XMLField can be replaced with TextField.
  • The undocumented mixin parameter to the open() method of
    django.core.files.storage.Storage (and subclasses) will be removed.

1.3¶

See the Django 1.1 release notes for more
details on these changes.

  • AdminSite.root(). This method of hooking up the admin URLs will be
    removed in favor of including admin.site.urls.
  • Authentication backends need to define the boolean attributes
    supports_object_permissions and supports_anonymous_user until
    version 1.4, at which point it will be assumed that all backends will
    support these options.
