I have found that Iran's Islamic Republic News Agency is a very accurate mirror of what the leadership of Iran is thinking, and as such it is a valuable tool to see if there are any changes in Iran's attitudes and methods in its quest to destroy Israel and the US.
As usual, there are still articles quoting "scholars" that the US and Israel is the source of all evil. These sorts of article, usually quoting Lebanese and Indian "scholars", have been a staple at IRNA. Even so, apparently it is OK to speak to Satan when it is convenient.
Islamic supremacism is still there but there is an interesting nod towards multiculturalism, in speaking a bit less of Islam and more of "divine religions" which include Christianity, Judaism and Zoroastrianism as being implacably opposed to the West. As Muslims are wont to do, they promote "dialogue" as a means to spread their message and to ignore the ideas of the supposed partners in conversation.
This means that they are positioning themselves not only as the center of Islam, but as the center of all "divine religions." Clearly they are trying to broaden their appeal beyond the Islamic world in their attempt to dominate the world.
They remain completely intractable on nuclear technology even as they pretend that it is only for peaceful purposes.
So in most cases there haven't been any real changes but even the small differences need to be watched carefully.
