This version of Ksetiwatch is designed for KDE 2.x and Qt 2.2.x. Additionally, you will need SETI@home 2.0 or higher to make full use of this program. Beginning with Ksetiwatch 2.1.0, clients with version number 1.x are not supported any more (this is not a problem, of course, since only the latest version of the client (3.03) is allowed to be used) . You can get the SETI@home client at the SETI@home web site.
You can find a list of changes at http://ksetiwatch.sourceforge.net/ChangeLog.
