The Amazon Kindle line of e-readers have just received a new firmware update for every Kindle after the Paperwhite 2. This is a relatively minor upgrade that puts the priority on new sorting functions for your library. You can now sort by samples, Kindle Unlimited and Prime Reading materials, and all of these books will be in dedicated sections. There is also the normal bug fixes and general enhancements found in version 5.11.2.
If you have installed the update and do not see the new sections right away, please do a reboot and you should start seeing the new sorting options in the library section.
