Description Florian Rivoal 2017-12-01 06:44:52 PST 
The update media query from Media queries level 4 let people tell apart media that responsively update the screen, from those that cannot, or those that can but only slowly.

Authors can use that to style things differently on print vs ebook readers, even though both media are paginated. This kind of nuance was not possible to express just with @media print {...}

The specification is over here:
