Here’s what they say:
Sharing Passages & Notes to Facebook: our last release saw highlighting, and now you can share what you highlight with your friends on facebook. Share quotes, passages, even your annotations with one tap directly to facebook.
Brightness and Rotation Lock Controls: We wanted our users to have fine control over the brightness of their screen (including the extremely popular Night Mode) and whether they read in portrait or landscape.
Share a Book Recommendation to Facebook: We all like to show off sometimes, and it’s OK! You can now post what you’re reading to your facebook wall with one tap.
Now if only Kobo could figure out to right-justify text !!!!
Right justified text on an e-reader often looks very bad. A lot of e-books are not formatted well and left justified works better for a small screen.
