Here's some of the new things I found in the manual:
1) collections can now be created and managed on the device (yay!).
2) zoom level can be locked so it's not reset when changing pages
3) clock is available by pressing Options key
4) going to previous page (after following a link) is now shorter (Options-Previous View)
5) you can switch the dictionary during look-up, no need to go to Options
6) you can set a picture (or several) or a text message as "standby screen".
7) auto-sleep after 10 minutes, auto-shutdown after two days
8) press and hold Options key to return to the book list
9) press Zoom button (loupe with + inside) and ">" to zoom the page by 10%
10) double-tapping a word in dictionary view will look it up in the same dictionary
11) Reader stores the list of looked up and searched words (Options-Word Logs)
12) double-tap to center and zoom a picture (in zoom mode)
