Change Missing From Changelog: forEach() Loop's `Return` returns to forEach()'s invocation point, not to the calling function.

Hey all,

I'm noticing that in upgrading to ReactJS Version 16.12.0 from 16.7.0, the behavior of foreach was changed, so that return returns to where foreach is called, and not the function calling the function containing the foreach. But I don't see this change here:

https://github.com/facebook/react/blob/master/CHANGELOG.md

Basically,

function1() {
	function2();
	console.log("function 1");
}

function2() {
	const arr = ['cool'];
	arr.forEach((var) => {
		return var;
	});
	console.log("function 2");
}

Before 16.12.0, console output was: "function 1", but now it is "function 2; function 1." This change appears to be against MDN documentation and internet consensus: https://stackoverflow.com/questions/34653612/what-does-return-keyword-mean-inside-foreach-function

But it should have been included in the changelog, though I am not seeing it. Let me know if I'm misunderstanding.

Inizia da CHANGELOG.md e dalla voce del changelog di React 16.12.0 a cui fa riferimento l’issue. Verifica il comportamento segnalato di forEach() in base ai riferimenti collegati di MDN e Stack Overflow, quindi determina se nel changelog manca una voce; l’attività è completata quando il report è convalidato e il changelog riflette correttamente la release, se appropriato.
