Kindle Paperwhite Software Update 5.3.0

The update includes improved fonts, UI enhancements, better manga support and the ability to turn off recommended content on the home screen.

On a side note, updating the Kindle is still a fairly old-school process. I downloaded a .bin file, dumped it on the Kindle via USB, and had to manually start the install. Seeing a Kindle reboot is still really weird, too.
