k-pacs manual for version 1.5

  • Hi
    I downloaded and installed K-pacs 1.5. When I tried to download the manual only 1.2 version manual is shown on the web site.
    Surely there should be extra useful features in 1.5.
    Is there any updated manual for the new version?
    I noticed in one of the discussions that the twain scanner works only for 8 bit images. I intend to scan the old anlog films as 16 bit like the latest CR and DR imges. Why is not possible?
