It has the following changes from WebKit's model: - Return a FrozenArray, instead of an array - Keep returning the same object until changes are made, instead of returning a new object each time. (This helps make dataTransfer.types === dataTransfer.types, which is false in Chrome currently.) The spec pull request is up at https://github.com/whatwg/html/pull/1860, with web platform tests (unfortunately manual) available at https://github.com/w3c/web-platform-tests/pull/3871
