+* If using SASS, you may need to update your ``custom.scss`` and/or
+  ``_variables.scss`` files accordingly to support Bootstrap 4.5. To see what
+  you might need to change in your ``_variables.scss``, see `the variables diff

+* It is assumed that all CodeRed CMS sites prior to 0.19 are using the built-in
+  Wagtail Image model, as this was previously hard-coded in CodeRed CMS. If (and
+  only if) you plan to switch to a custom image model, a custom data migration
+  will be necessary. This migration would follow the same process as any other
+  Wagtail installation; there is nothing unique relating to CodeRed CMS.
 
 * You may need to run ``python manage.py makemigrations website`` and
   ``python manage.py migrate`` after upgrading.
