title: The url() function in Django has been deprecated - Do I have to change my source code?
body: <p><a href="https://docs.djangoproject.com/en/3.1/ref/urls/" rel="nofollow noreferrer">The url() function</a> in django has been deprecated since version 3.1. Here's how backwards compatibility is being handled;</p>
  <pre><code>def url(regex, view, kwargs=None, name=None):
      warnings.warn(
          'django.conf.urls.url() is deprecated in favor of '
          'django.urls.re_path().',
          RemovedInDjango40Warning,
          stacklevel=2,
      )
      return re_path(regex, view, kwargs, name)
  </code></pre>
  <p>For now, re_path() is returned when the url() function is called. When the function is completely removed, will the projects that use it have to change their source code?</p>
