On Saturday Iran published 'new' demands for the reopening of the Strait of Hormuz:

[Secretary of Iran's Supreme National Security Council Mohammad Baqer Zolqadr] said the US should observe the six following conditions:

"1. Never, and in no language, threaten Iran or insult the sanctities of this nation.

2. Permanently end the war and aggression against Iran and Iran's allies in Lebanon, Palestine, Yemen and Iraq.

3. Lift the naval blockade and withdraw its military forces (naval and air) from around Iran.

4. Pay in full, without any reduction, the damages caused to Iran by the two wars of aggression and imposition.

5. Lift the unjust and illegal sanctions against the Iranian nation.

6. Unconditionally release the blocked and stolen assets of the Iranian people."

These demands seem to have confused U.S. observers. The Wall Street Journal claimed (archived) that these were somehow more harsh than those which had been previously issued:

[..] Iran insisted Saturday on its highest price yet for permitting the free flow of traffic in the waterway, seeking billions of dollars in U.S. payments, the removal of American troops from the region and an end of the U.S. naval blockade, among other things.
…
"Iran's recent hardline demands for reopening the strait make it increasingly difficult for the president to manufacture a face-saving off-ramp from the conflict," said Mona Yacoubian, director of the Middle East program at the Center for Strategic and International Studies, a Washington think tank.

The WSJ author and his 'expert' are mistaken. There is nothing new in the Iranian demands. They are direct repetitions of clauses laid down in Memorandum of Understanding which the White House had negotiated and President Trump had publicly signed.

Point 1 of the MoU notes that the parties "undertake .. to refrain from the threat or use of force against each other" which is similar to point 1 of the 'new' conditions.

Point 1 of the MoU also had the parties "declare the immediate and permanent termination of military operations on all fronts, including in Lebanon, …". This is repeated, and spelled out in more detail, in point 2 of the new conditions.
