I'm glad to announce the long awaited release of the Qt4 version of the WebIssues client. It now runs natively on both Windows and Linux platforms. Windows users can use the installer which takes care of installing all necessary libraries. Linux users will need Qt4 and CMake to compile the application. Some binary packages will be provided as well in near future.
I also created a user's manual for the client, making the development officially reach the beta stage. In a month or so I will release another version with more functional improvements along with a new version of the server with it's own manual and some small fixes.
