Slightly updated version is here:
http://lbook.ua/templates/files//V3u...2-20091030.rar
no new features compared with V3update-uk-2.22-20091024.rar, just some small bug fixes. It is an official firmware.
The firmware from 20091102 is a test version of new features of Coolreader. And indeed it is based on June (not April) Lbook firmware, so there are no new features for pdf or epub. But if you open a Fb2 file with it, you can see all the changes mentioned by
