This is a copy paste from Email I recieved from Amazon this week. They told me that If I had on my wireless, that the update the latest version would happen automatically, and that it would install itself when in "sleep" mode. I monitored every day to see when it would happen, and today Saturday, I notice some of the new features, especifically, the "Real Page Numbers" which was one of the "dislikes" I had about the Kindle - actually the "Book" or "Publication" needs to support this feature.
Real Page Numbers
Many titles in the Kindle Store now include real page numbers, making it easy to reference and cite passages and read alongside someone reading the print book in a book club or class. Page numbers will also be available on our free "Buy Once, Read Everywhere" Kindle apps in the coming months. As with all of Kindle's features, we want you to lose yourself in the author's words, so page numbers and locations are only displayed when you press the Menu button.
This feature lets Kindle users choose to make their book notes and highlights available for others to see. Any Kindle user -- including authors, their fans, book reviewers, professors and passionate readers everywhere -- can opt-in to share their thoughts on book passages and ideas with friends, family members, colleagues, and the greater Kindle community of people who love to read. To review and turn on Public Notes in your own books, view the Public Notes of people you follow, track your reading activities, see Popular Highlights and your annotations, and view your full library of books, go to https://kindle.amazon.com
Before You Go ...
When you reach the end of the book, you can now immediately rate the book, share a message about the book with your social network, get personalized recommendations for what to read next, and see more books by the same author.
New Newspaper and Magazine Layout
A new browsing layout makes it easy to scan newspapers and magazines more quickly.
