Well we at least have that, that's great to hear. Does anyone know if Calibre already does this? CSS hyphenation?

There was also nothing in the CSS (other than the hyphen code) that shouted "enhanced typesetting" to me.

That's weird, since Amazon seemingly is indeed processing the books to have the new typesetting. I'm no expert in how ebook files are constructed, but is it possible that Amazon is actually processing the book content itself? Perhaps they added
hyphenation markers to the actual content, for example. Perhaps they also did something similar (perhaps proprietary) for the rest of the typesetting? I imagine it would be a matter of inspecting the actual book content. My guess would be that they added some sort of hinting markers, such as soft hyphens, to facilitate the new typesetting. It's unfortunate that it's not as simple as some metadata toggle or CSS directive.
