KDE Development Platform 4.5.0 gains performance, stability, new high-speed cache and support for WebKit

KDE, an international Free Software community, proudly announces the release of the KDE Platform 4.5. This basis for the Plasma Workspaces and Applications developed by KDE 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 KDE development. KDE Platform has progressed in many areas, both in terms of infrastructure and of development tools.

These changes form the underpinnings for many improvements in Plasma Desktop and Plasma Netbook and in the KDE Applications 4.5 that have been released in tandem with the KDE Development Platform 4.5.0.

Plans and Work in Progress

The KDE platform team is working on making the KDE Platform more suitable for mobile devices. With the introduction of KDE's platform profiles, it is possible to compile KDE with limited feature sets in order to minimise their footprint. These profiles are still being elaborated to meet mobile apps' needs. The plans include using it for the mobile versions of Kontact, KOffice and the Plasma Mobile workspace. The BlueDevil framework will add better support for many Bluetooth devices in upcoming versions. BlueDevil, which is based on BlueZ, found on many Linux systems, is maturing quickly and is currently going through a series of beta releases. Its developers are aiming at a release included with the KDE Platform 4.6 in January 2011.

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 4.5.0 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 4.5 Info Page.

Compiling 4.5.0

The complete source code for 4.5.0 may be freely downloaded. Instructions on compiling and installing KDE software 4.5.0 are available from the 4.5.0Info 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 4.6.3. 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.
