canvas as an optional ``peerDependency`, which apparently helps with Yarn PnP support.nonce property from HTMLScriptElement and HTMLStyleElement to HTMLElement. Note that it is still just a simple reflection of the attribute, and has not been updated for the rest of the changes in whatwg/html#2373.Headers class from the Fetch standard.element.translate getter and setter.XMLHttpRequest on the newly-released Node.js v12.form.elements to exclude <input type="image"> elements.pattern="" form control validation to apply the given regular expression to the whole string. (kontomondo)Several potentially-breaking changes, each of them fairly unlikely to actually break anything:
JSDOM.fromFile() now treats .xht files as application/xhtml+xml, the same as it does for .xhtml and .xml. Previously, it would treat them as text/html.Blob or File constructor with the endings: "native" option, jsdom will now convert line endings to \n on all operating systems, for consistency. Previously, on Windows, it would convert line endings to \r\n.
