DeprecationWarning with Django 1.5

When running Nexus with Django 1.5 release candidate with warnings turned into errors and tracebacks enabled, I get this:

    File "nexus/sites.py", line 57, in get_urls
      from django.conf.urls.defaults import patterns, url, include
    File "django/conf/urls/defaults.py", line 3, in <module>

    DeprecationWarning: django.conf.urls.defaults is deprecated; use django.conf.urls instead
