The url and ssi template tags will be modified so that the first\nargument to each tag is a template variable, not an implied string. In 1.4,\nthis behavior is provided by a version of the tag in the future template\ntag library.

Translations located under the so-called project path will be ignored during\nthe translation building process performed at runtime. The\nLOCALE_PATHS setting can be used for the same task by including the\nfilesystem path to a locale directory containing non-app-specific\ntranslations in its value.
The Markup contrib app will no longer support versions of Python-Markdown\nlibrary earlier than 2.1. An accelerated timeline was used as this was\na security related deprecation.

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

Note that this\nmeans that the admin application will depend on the messages\ncontext processor.

Authentication backends will need to support the AnonymousUser class\nbeing passed to all methods dealing with permissions. The\nsupports_anonymous_user variable will no longer be checked and can be\nremoved from custom backends.
The ability to specify a callable template loader rather than a\nLoader class will be removed, as will the load_template_source\nfunctions that are included with the built in template loaders for\nbackwards compatibility.
django.utils.translation.get_date_formats() and\ndjango.utils.translation.get_partial_date_formats(). These functions\nwill be removed; use the locale-aware\ndjango.utils.formats.get_format() to get the appropriate formats.

django.db.models.fields.XMLField will be removed. This was\ndeprecated as part of the 1.3 release. An accelerated deprecation\nschedule has been used because the field hasn't performed any role\nbeyond that of a simple TextField since the removal of oldforms.\nAll uses of XMLField can be replaced with TextField.
