What does that mean for you?
Today the first Beta of KDE 4.0 has been released. This means, the basic libraries, frameworks, apis… are frozen from today.
On big point about this: application developers may start to build their applications on solid APIs.
Also, those libraries now can be ported to platforms like Mac OS X and Windows. So in the next few weeks/months, the first KDE applications will come to other platforms. Tomorrow I will introduce one or two applications to you… so stay tuned.
