CB 3 for Magento 2
Version 3.3.0
If you have template customizations or custom views using Bootstrap or FontAwesome icons.
CB 3.3.0 uses Bootstrap 4.6 instead of Bootstrap 3 and minor amends to template styling using layout, button, forms and modals may be necesary. See the Bootstrap 4 migration guide. Also, we upgraded the FontAwesome icon library from version 4 to 5. See the FontAwesome migration guide.
