Based on this quote from the 4.17 release notes, does this mean that the entirety of 4.18 will not work in IE11 or that only new features will not work? It reads as if the whole API won't work, but I'd like to make sure.
Version 4.17 will be the last release with support for Internet Explorer 11 and Edge Legacy browsers. This means that apps built with 4.18 (and beyond) will not function in IE11/Edge Legacy.
