* Updated compatibility for Django 1.11, 2.1, 2.2 and 3.0 in line with Django's
supported versions policy.
* Numerous improvements to the Bootstrap 4 template pack, which may now be
considered mature.

Here are some changes that might affect custom templating you already have in
place when using Bootstrap 4 :

 * Using [Custom Forms for radio and checkbox](https://www.w3schools.com/bootstrap4/bootstrap_forms_custom.asp).
   You may disable this by setting  `FormHelper.use_custom_control = False`.
 * Using [Bootstrap 4 `"form-row"` class in place of `"row"`](https://getbootstrap.com/docs/4.3/components/forms/#form-row).
 * Fixing [layout hierarchy between input and its label for checkbox and radio](https://getbootstrap.com/docs/4.0/components/forms/#checkboxes-and-radios).
