Improved Multimedia and Semantic Capabilities in KDE Platform

Wednesday, 27 July 2011

KDE proudly announces the release of KDE Platform 4.7. 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 done on improving the performance and stability of the underlying structure.

The latest version of Phonon, our media framework, now comes with many new features such as Zeitgeist support. We have also worked on back-ends: The VLC-based back-end is now considered stable and is the preferred back-end for multiplatform use, while the back-end based on GStreamer is now also considered stable on Linux platforms. The xine back-end is no longer maintained.

The semantic desktop components of the KDE Frameworks have improved functionality and stability. Nepomuk has undergone massive internal changes making it more stable and faster, with richer APIs for applications. Strigi analyzers now read meta-data in their own process, resolving over 35 crash-related bugs in Dolphin and Konqueror.

KWin now features an option for application developers to suspend compositing when a fullscreen application calls for it. This should increase performance for OpenGL games and GPU-accelerated video playback.

KDM, the display manager, has gained GRUB2 support. A user with multiple operating systems in their GRUB2 menu can now choose which one to reboot to in the shutdown dialog by holding down the mouse button on their reboot choice.

KIO Proxy, KDE's system-wide proxy support continues to be overhauled with fixes and features including SOCKS proxy support, functions for obtaining multiple proxy URL addresses and support for obtaining system proxy information on the Windows and Mac platforms.

KwebkitPart, integrating WebKit into KDE applications, has improved ad-blocking support, making browsing with a KDE WebKit browser a more pleasant experience.

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 and can also be obtained on CD-ROM or with any of the major GNU/Linux and UNIX systems shipping today.

Packages. Some Linux/UNIX OS vendors have kindly provided binary packages of 4.7.0 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 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 4.7 Info Page.

The complete source code for 4.7.0 may be freely downloaded. Instructions on compiling and installing KDE software 4.7.0 are available from the 4.7.0 Info Page.

System Requirements

In order to get the most out of these releases, we strongly recommend to use the latest version of Qt, as of today 4.7.4. 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.
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.
