Ray Detail Region - What is this and what is Ray Detail Region Padding?
So this is Disney World.  Can we live here?

See the changelog entry:
"Two new render settings on the Advanced tab which control the region in which ray traced polygons are fully subdivided. Outside of this region the ray traced polygons are only coarsely subdivided. Previously this region was the frustum seen by the rendered image or crop region, but now you can also choose to have no detail or to have detail everywhere within the camera frustum regardless of crop settings. "Ray detail region padding" can be used to enlarge (or shrink) the region. A value of 0 means no padding. A value of 1 adds a border to each side of the frustum which is equivalent to the width or height of the image or crop region, which makes the frustum 3 times as wide and 3 times as tall."

This and many other settings will be added to the Node Reference shortly, as we finish converting to our new system.

I think this covers the issues myself and some others came up against as discussed here. I'm sure it will have other uses too :)

@neuspadrin - But, what is the difference in your test between the first and the third visually?

thats the whole point.  the third render was cropped, the first was not.

so people who want a nice huge render but their computer cant handle it, or they want to slowly build it and have stopping points, they can crop the image into areas while using the detail from camera instead of crop such that the shadows match up.

the left side is one crop, the right side is the other crop, look at the bottom line that goes red to green to see when the crop happens.  if you notice in the second one, following that line is where shadows distort and act funny and doesn't add up together as nice + shadows on the right look funny and non realistic.  In the third one i did the exact same crop, but the shadows are correct and match up etc.

I understand the second.  The first and third still do not make sense...to me.
