[Interest] where can I find newest import versions (QML)

[ekke]

updating to a new Qt version I'm also updating my imports in .qml

Who knows where to find the newest import versions ?

import QtQuick 2.8
import QtQuick.Layouts 1.3
import QtQuick.Controls 2.1
import QtQuick.Controls.Material 2.1

QtCreator doesn't help always - per ex. only lists QtQuick up to 2.5

thx
