Shadow DOM v0

Chrome and other browsers implemented the new version, see https://www.chromestatus.com/features/4667415417847808. V0 is scheduled for deprecation starting in April 2018 and removal in April 2019. If you are still using this consider migrating to the new API or upgrading your Polymer library. Use --disable-blink-features=ShadowDOMV0 for testing if your site works without Shadow DOM V0 APIs.

Comments

Updated IE views based on http://status.modern.ie/#/ ("Under consideration"). Latest spec: see also dev.w3.org/csswg/shadow-styling/ for the styling aspects.
