Support for Bootstrap 3 was added in AppStudio 6. Since then, Bootstrap 4 has been released.

There are many changes in Bootstrap 4: more than we could build a migration for in AppStudio 7. We ended up making Bootstrap 4 a separate framework. We will continue to support Bootstrap 3 for existing projects, but recommend using Bootstrap 4 for new projects.

We were able to make most of the changes in our code, so the controls work pretty much the same way. The code emitted by AppStudio is quite different.

Since Bootstrap 3 and Bootstrap 4 share many internal variable names, controls from the two frameworks cannot be included in the same project.
