+<div>ECMAScript 7 é a nova evolução do padrão ECMA-262 (normalmente referenciado como <a href="https://developer.mozilla.org/pt-BR/docs/Web/JavaScript">JavaScript</a>). Antes mesmo que o ECMAScript 6 fosse finalizado em 17 de Junho de 2015, novas funcionalidades já haviam sido propostas. Você pode conferir essas propostas no repositório <a href="https://github.com/tc39/ecma262">tc39/ecma262</a> do GitHub.</div>
+
+<div><br>
+Os problemas atuais com o processo das especificações foram solucionados ao adicionar <em>estágios </em>e <em>campeões</em> para os conjuntos de funcionalidades. Também, um ciclo de dois anos para as padronizações foi proposto. Para maiores informações sobre o processo de especificação do post-ES2015, veja essa <a href="http://slides.com/rafaelweinstein/tc39-process">apresentação feita pelo Rafael Weinstein</a>.</div>
