Omission of Javascript File

I am glad to see support for the latest implementation of bootstrap, however, twitter-bootstrap 4 requires the following javascript files (in order):

  1. jQuery version 3.2.1
  2. popper version 1.12.3
  3. bootstrap version 4.0.0-beta.2

It appears as though after the update, bootstrap studios included #1 and #3, but have omitted #2.

Thanks for this report! In Beta 2 Bootstrap started bundling popper together with the bootstrap js file, so there is no need for a separate include.
