Sorry that duplicate theme, but in Dev thread haven’t response for few days .  
Why does mautic use so old [bootstrap](https://getbootstrap.com/)library (3.1.1 version - with available 5.2 )?

Is any ideas how to upgrade bootstrap js to latest version ? - Or it will crash all js actions and other bundles ?

Thanks
