the firmware can be found here:
FW 302_15.4alpha
It's the first alpha version with the function of making notices directly in the book - at the moment only with fbreader, in the final version also in the ADE.
Some bugs are corrected (zooming by wiping up and down the right screenside...), the new feature works good, but some things could be better - very small icons in the book-menu (while reading tapping the center of the screen)... but I hope, it will become better!
