问题
I'm using the Select2 control along with the Select2.Multi-checkboxes.JS plugin to allow multi-checkbox selection.
The following demo shows that the control works properly with Select2 3.x:

But when I cloned from this my own fiddle with Select2 4.0.x it stopped working. The checkboxes are no longer presented. What's the issue?

I copied all the elements from Fiddle 1 to Fiddle 2 by doing a direct Fork (Clone). Nothing was changed manually in the code. I only deleted the prior Select2 CSS/JS and replaced them with 4.0.5. The Select2-MultiCheckboxes JS is exactly the same.
Also here's a JSFiddle where I updated the Raw Multi-Checkbox JS reference, the previous one had a Version 3.5 reference in its name: https://raw.githubusercontent.com/wasikuss/select2-multi-checkboxes/master/select2.multi-checkboxes.js I assume this is the latest one?
http://jsfiddle.net/oa435z7s/2/ This is even worse.
Is there a new version of Select2.Multi-Checkboxes.JS that works with Select2 4.0.x?
