KDE Platform 4.8 Enhances Interoperability, Introduces Touch-Friendly Components

KDE proudly announces the release of KDE Platform 4.8. KDE Platform is the foundation for Plasma Workspaces and KDE Applications. It has seen significant improvements. Besides the introduction of new technology, a lot of work has been done on improving the performance and stability of the underlying structure.

Qt Quick is making its way into Plasma Workspaces. The new Plasma Components provide a standardized API implementation of widgets with native Plasma look and feel. For example, the Device Notifier widget has been ported using these components and is now written in pure QML. KWin's Window Switcher is now also QML-based, paving the way for easier design of new window switchers. The introduction of QML into the Plasma Workspaces significantly lowers the barriers for new developers to improve the Workspaces or use Plasma as the basis for other products.

The new Plasma QtQuick Components bring a standard set of user interface elements to Plasma. These new components bring a standardized API and implementation of common UI elements. Plasma Components offer an efficient, elegant and powerful set of widgets, which integrate well with the underlying platform. Combined with Plasma's visual and data integration components, application development has never been easier, more fun and powerful. Plasma Components automatically adapt to the device they are used on, making it easy to share code between Desktop and mobile and touch-based applications and allowing deployment and usability on a wider range of target devices.

KSecretService is a new framework for sharing saved passwords and other credentials between a wider range of applications. KSecretService uses KDE's well-known interfaces through a Freedesktop-compliant API with other password systems, transparently for the user. KSecretService improves integration of KDE applications into other workspaces and allows 3rd party applications to plug into KDE's secure password saving system.

The KDE team is currently working on the next iteration of the KDE Development Platform under the codename "Frameworks 5". While Frameworks 5 will be mostly source compatible, it will be based on Qt5. It will provide more granularity, making it easier to use just parts of the platform, and reducing dependencies considerably.

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 and CPU architectures such as ARM and x86, 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. Plasma Active is a user experience for a wider spectrum of devices, such as tablet computers and other mobile hardware.
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.

Packages. Some Linux/UNIX OS vendors have kindly provided binary packages of 4.8.0 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 4.8 Info Page.

The complete source code for 4.8.0 may be freely downloaded. Instructions on compiling and installing KDE software 4.8.0 are available from the 4.8.0 Info Page.

System Requirements

In order to get the most out of these releases, we recommend to use a recent version of Qt, either 4.7.4 or 4.8.0. This is necessary in order to assure a stable and performant 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.
