select2 javascript need to update

I’ve installed your great plugin for my new website, under construction and, with my site in debug mode, find that the select2 JavaScript, use a non valid function. I correct this installing the new library version https://github.com/select2/select2/releases/tag/4.1.0-rc.0

Thanks for your great plugin
