saved.shift is not a function

1. @mgol we hit this in Bootstrap 4.x https://travis-ci.org/twbs/bootstrap/jobs/519620443

   Going back to 3.3.1 our tests pass.

2. Can we at least get a stack trace?

   My second comment includes a stack trace.

   AFAICT it only affects IE 10,

   Chrome too.

3. There’s no set date, but it will probably be next week or the week after.

4. I just broke production because of this bug.

   GitHub currently pushes recommendations to all repos using jquery <3.4.0 to upgrade due to CVE-2019-5428. I saw that, so I checked out the release blog post which currently says:

   There should be no compatibility issues if upgrading from jQuery 3.0+.

   So after some brief sanity testing (which seemed fine) I deployed and then errors started arriving.

   Given this bug, I recommend you change the wording on the blog post for 3.4.0.

5. Any word on when a 3.4.1 release will be cut?

6. jQuery 3.4.1 has been released! https://blog.jquery.com/2019/05/01/jquery-3-4-1-triggering-focus-events-in-ie-and-finding-root-elements-in-ios-10/
