Along with the existing specced IDL changes Chrome also has the below changes

interface mixin ParentNode {
  [Unscopable, RaisesException, CEReactions] void prepend((Node or DOMString or TrustedScript)... nodes);
  [Unscopable, RaisesException, CEReactions] void append((Node or DOMString or TrustedScript)... nodes);
  [Unscopable, RaisesException, CEReactions] void replaceChildren((Node or DOMString or TrustedScript)... nodes);
};

interface mixin ChildNode {
  [Unscopable, RaisesException, CEReactions] void before((Node or DOMString or TrustedScript) ... nodes);
  [Unscopable, RaisesException, CEReactions] void after((Node or DOMString or TrustedScript)... nodes);
  [Unscopable, RaisesException, CEReactions] void replaceWith((Node or DOMString or TrustedScript)... nodes);
};
