oh sorry. My question was what is different in this custom-elements.js from CustomElement.js in https://github.com/WebComponents/webcomponentsjs? I know this directory is moved from there. But I would like to know the difference and reasoning behind it. Thanks!

Not sure but I think they created a new separate project for the Custom Element polyfill for the needs of the "version 1" implementation.
You shouldn't use the old one since it is not updated any more. It supports only the old specfication.

Correct. https://github.com/webcomponents/custom-elements is for the v1 CE polyfill. We broke up each polyfill into a separate repo.
https://github.com/WebComponents/webcomponentsjs is v0 APIs.
