NodeList is no more compatible with Array<Node>. Breaking change in 3.0

TypeScript Version: Version 3.0.3

Code

I didn't find any mentioning to this breaking change.

This code used to compile in 2.9.2:

/**
 * Array based implementation of NodeList
 */
class JSArrayNodeList extends Array<Node> implements NodeList {
	constructor(items?: Array<Node>) {
		if (items) {
			super(...items);
		} else {
			super();
		}
	}

	public item(index: number): Node {
		return this[index];
	}

	public copy(): JSArrayNodeList {
		return new JSArrayNodeList(this);
	}
}

In 3.0 forEach method of NodeList and Array became incompatible.
Due to this changeset: https://github.com/Microsoft/TypeScript/commit/7a7d04e126fb7c1c6074ef26657eddb0f32e4003

A solution was to add explicit forEach which delegates call to super:

/**
 * Array based implementation of NodeList
 */
class JSArrayNodeList extends Array<Node> implements NodeList {
	constructor(items?: Array<Node>) {
		if (items) {
			super(...items);
		} else {
			super();
		}
	}

	public forEach(
		callbackfn: ((value: Node, index: number, array: Node[]) => void) | ((value: Node, key: number, parent: NodeList) => void),
		thisArg?: any): void {

		// Just call Array.forEach
		Array.prototype.forEach.call(thisArg, this, callbackfn);
	}

	public item(index: number): Node {
		return this[index];
	}

	public copy(): JSArrayNodeList {
		return new JSArrayNodeList(this);
	}
}

Expected behavior:

Documentation in breaking change list.

Actual behavior:

No information about breaking change.

Locate the TypeScript 3.0 breaking changes documentation and review how compatibility changes are listed. Document that NodeList and Array forEach signatures became incompatible, including the affected version and the migration context shown in the issue. Done means the breaking change is clearly included in the relevant list.
