This just came out. Don't know exactly what it's for. This is from Amazon:
We have a new, free software update available for Kindle Paperwhite. The software update will be delivered wirelessly and includes general improvements for your Kindle Paperwhite. This update automatically downloads and installs for Kindle Paperwhite customers; however, you can also manually download the software and update your device via USB cable.
Here's the link: http://www.amazon.com/gp/help/customer/display.html/ref=hp_left_sib?ie=UTF8&nodeId=201064850
Edit -- 5.3.4 released in mid March, 5.3.5 released in late April -- link should take you to most recent version. -- Ann
