Below is a list of caveats when migrating from Bootstrap3/django-bootstrap3 to Bootstrap4/django-bootstrap4.
This document only considers the differences between django-bootstrap3 and django-bootstrap4. For the migration guide from Bootstrap 3 to 4, please look at the Bootstrap docs, especially the [Migration section](https://v4-alpha.getbootstrap.com/migration/).
Bootstrap 4 does not ship with an icon set, so everything regarding to icons has been removed.
If you need easy access to icons that are compatible with Bootstrap 4, please consider https://github.com/zostera/django-fa.
