Amazon rolled out a new update for their Android app earlier this week, but it looks to be a relatively minor update.
The “what’s new” page for this update doesn’t mention any major new features, but it does say that the app now offers more margin and line spacing options. And the update brings bug fixes, of course. I also looked behind the scenes and the update doesn’t appear to have any unannounced features (like support for KF8 format).
BTW, I check behind the scenes because Amazon doesn’t always mention new features. For example, the latest update for Kindle4PC dded support for KF8, only Amazon didn’t mention it. I’m not sure why they wanted to keep us guessing, but it does make life interesting.
