Recently I’ve become the maintainer of the KDocker project. KDocker is a Qt application what allows you dock any application into the system tray. It currently supports any X Windows system. What I’ve done for the 4.0 release is, move the project to launchpad (Girish, the creator of the project is locked out of the Source Forge page) and port/re-write the entire app to use Qt 4.
The port/re-write to Qt 4 is complete and I’ve released it. The version has jumped from 1.3 to 4.0 to better illustrate the the severity of this change. Also, it takes it to a similar version scheme to Qt and KDE.
There are a few things to note about this release and KDocker in general. For this release session management and auto starting have been removed. This is mainly because modern desktop environments support both of these very well. Also, I believe that environments that do not support this are better of using a dedicated application instead of having the functionality rolled into a docker. Another point to note is KDocker 4.0 as well as the older version are pure Qt and Xlib applications. They do not depend on KDE.
