Mobile Target Makes KDE Platform Lose Weight
KDE Releases Development Platform 4.6.0
January, 26th 2011. KDE proudly announces the release of KDE Platform 4.6. The foundation for the Plasma workspaces and the KDE applications has seen significant improvements in many areas. Besides the introduction of new technology, a lot of work has been spent on improving the performance and stability of the underlying pillars of the Platform.
Low-Fat Mobile Profile Cuts Dependency Chains
By modularizing the KDE libraries further, parts of the KDE platform can now be built for mobile and embedded target systems. Reduced cross-library dependencies and allowing certain features to be disabled, allow KDE frameworks to now be easily deployed on mobile devices. The mobile profile is already used for mobile and tablet versions of KDE applications, such as Kontact Touch, KDE's mobile office suite and the tablet and handset Plasma user interfaces.
Harness the Power of Plasma with QML
UPower, UDev and UDisks Support, Metadata Backup
Thanks to Solid's new UPower, UDev and UDisks backends, the deprecated HAL is no longer needed to manage hardware on Linux. Applications do not need to be updated to make use of these new backends. The HAL backend is still available for systems that do not support UPower.
Nepomuk, the semantic desktop technology of the KDE Platform, gained backup and synchronisation support to make transferring meta-data between devices easier. Users can now back up their semantic data using a graphical interface. Additional synchronization features are currently only available from the command line.
KWin Becomes Scriptable, Oxygen-GTK Improves cross-desktop Integration
Kwin, KDE's window and compositing manager now has a scripting interface. This gives advanced users and distributors more power over the behavior of windows in a KDE Plasma workspace – for example it is possible to set a window as “keep above” until the window is maximized, treating it as a normal window that can be covered when maximized. When the window is un-maximized, automatically set it as “keep above” again. The KWin team is currently working on support for OpenGL-ES, expected to be ready for prime-time with the release of 4.7 in summer 2011, so that KWin will be usable on handheld systems.
Oxygen, the visual component of the KDE Platform has also seen extensive work with a complete remake of all mimetype icons, the introduction of the Oxygen-GTK theme engine, enabling better integration of GTK apps into KDE Plasma Workspaces, including gradients and many of the features users expect from Oxygen.
New Bluetooth Framework Allows Easy Device Pairing
BlueDevil, a brand new Bluetooth framework, allows easy device pairing and management. BlueDevil replaces KBluetooth and builds on top of the BlueZ stack. It allows the following:
- You can now use a wizard to pair devices,
- Browse files on bluetooth devices using Dolphin or Konqueror, and
- Manage bluetooth settings from KDE’s System Management or the system tray.
- The new framework also ‘listens’ for incoming requests, for example, to receive files or to enter a PIN code.
Installing the KDE Development Platform
KDE software, including all its libraries and its applications, is available for free under Open Source licenses. KDE software runs on various hardware configurations, operating systems and works with any kind of window manager or desktop environment. Besides Linux and other UNIX based operating systems you can find Microsoft Windows versions of most KDE applications on the KDE software on Windows site and Apple Mac OS X versions on the KDE software on Mac site. Experimental builds of KDE applications for various mobile platforms like MeeGo, MS Windows Mobile and Symbian can be found on the web but are currently unsupported.
KDE software can be obtained in source and various binary formats from http://download.kde.org and can also be obtained on CD-ROM or with any of the major GNU/Linux and UNIX systems shipping today.
Some Linux/UNIX OS vendors have kindly provided binary packages of 4.6.0
for some versions of their distribution, and in other cases community volunteers
have done so.
Some of these binary packages are available for free download from KDE's http://download.kde.org. Additional binary packages, as well as updates to the packages now available, will become available over the coming weeks. Package Locations. For a current list of available binary packages of which the KDE's Release Team has been informed, please visit the 4.6 Info Page.
In order to get the most out of these releases, we strongly recommend to use the latest version of Qt, as of today 4.7.2. This is necessary in order to assure a stable experience, as some improvements made to KDE software have actually been done in the underlying Qt framework.
Graphics drivers may under certain conditions fall back to XRender rather than OpenGL for compositing. If you have issues with notably slow graphics performance, switching off desktop effects is likely to help, depending on the graphics driver and setup used. In order to make full use of the capabilities of KDE's software, we also recommend to use the latest graphics drivers for your system, as this can improve the user experience substantially, both in optional functionality, and in overall performance and stability.

Also Released Today:
The KDE Plasma Workspaces gain from a new Activities system, making it easier to associate applications with particular activities such as work or home tasks. Revised power management exposes new features but has a simpler configuration interface. KWin, the Plasma workspace window manager, receives a new scripting and the workspaces receive visual enhancements. Plasma Netbook, optimized for mobile computing devices receives speed enhancements and becomes easier to use via a touchscreen interface. For more details read the KDE Plasma Workspaces 4.6 announcement.
Many of the KDE Application teams have also released new versions.
