    Versão Descrição
    8.4.0 Métodos de obtenção (como SimpleXMLElement::asXML() ou SimpleXMLElement::getName()) e a conversão de um SimpleXMLElement para string não reiniciam mais implicitamente o iterador. O iterador agora deve ser reiniciado explicitamente, usando SimpleXMLElement::rewind(), quando necessário.
    8.0.0 SimpleXMLElement implementa Stringable, Countable, e RecursiveIterator agora.
