KDE 4.7 releases provide many new features and improved stability and performance. Lots of visual polishing took place with an update to the Oxygen icons, and improved consistency between panel items such as clock and notification areas. The window manager KWin brings a new shadow system and can now run on OpenGL ES supporting hardware, making it better suited for mobile devices. Network management widget is much improved. Navigating through applications and recent files is easier with the addition of breadcrumbs to the Kickoff application launcher. Kontact groupware solution rejoins the rest of the KDE software, with increased stability, better connection to new services and sharing of communication information between more applications.
