2.5 liter for the Maverick only?

So it is different.

What exactly were the changes done to it compared the the previous version?

Are there any articles showing the history of Ford's Atkinson 2.5L engines with the changes that were made between versions along with performance numbers.

An article for all changes? Hell if I know. I believe I read the compression ratio change is a result from just changing the volume of the pistons, presumably because a truck needs just a smidge more oomph than a sedan/people mover, even if it hurts mileage.

I respectfully disagree. I bought a 2005 FEH new and still have it today. While it is a 4 cylinder atkinson cycle engine, the displacement is 2.3 liters.

Yes, from 2005 to 2008 it was 2.3 liters but 2009-2011 the Escape was 2.5 liter. Same engine just different displacement

All of the Ford Atkinson engines (2.3, 2.5 and 2.0 liter used in Escape, Fusion, CMax, Mav) have relatively high compression ratios. Higher compression ratios result in high efficiency. They can get away with it due to the Atkinson cycle. It does not completely fill the cylinder with as much air as the Otto cycle. So cylinder pressures are not as high and therefore pre-ignition is reduced.

Is the Atkinson 2.5 liter engine used exclusively in the Maverick Hybrid or is it also used in other Ford vehicles? I know the 2.0 Ecoboost engine cover from other Fords can be transplanted to the Maverick 2.0 but I don't know about the 2.5.

I'm assuming you asked this question to try to find an engine cover, it seems the thread got derailed. Were you able to find a cover? If I'm wrong sorry to revive an old thread.
