September 12, 2014. KDE today announces the release of KDE Frameworks 5.2.0.

KDE Frameworks are 60 addon libraries to Qt which provide a wide variety of commonly needed functionality in mature, peer reviewed and well tested libraries with friendly licensing terms. For an introduction see the Frameworks 5.0 release announcement.

New in this Version

KActivities

reimplementation of the file item plugin for linking files to activities

KArchive

fix handling of uncompressed files

KConfigWidgets

fix missing default shortcuts for standard actions, leading to many runtime warnings

better support for QGroupBox in KConfigDialogManager

KCoreAddons

Mark KAboutData::setProgramIconName() as deprecated, it did not do anything. Use QApplication::setWindowIcon(QIcon::fromTheme("...")) instead.

new classes Kdelibs4ConfigMigrator and KPluginMetaData

KDeclarative

added org.kde.kio component.

KImageFormats

disable the DDS and JPEG-2000 plugins when Qt version is 5.3 or later

KIO

now follows the mime-apps spec, for better interoperability with gio when it comes to the user's preferred and default apps.

new classes EmptyTrashJob and RestoreJob.

new functions isClipboardDataCut and setClipboardDataCut.

KNewStuff

installing "stuff" works again (porting bug)

KWidgetsAddons

new class KColumnResizer (makes it easy to vertically align widgets across groups)

KWindowSystem

New method KWindowSystem::setOnActivities

KXmlGui

KActionCollection::setDefaultShortcuts now makes the shortcut active too, to simplify application code.

Threadweaver

The maximum worker count will now decrease if a lower value is set after workers have been created. Previously, workers would remain active once they have been created.

Examples from the previous ThreadWeaverDemos Github repository are being merged into the KF5 ThreadWeaver repo.

The maximum worker count can now be set to zero (the previous minimum was 1). Doing so will effectively halt processing in the queue.

Documentation of various aspects of ThreadWeaver use is becoming part of the KDE Frameworks Cookbook. Parts of it is located in the examples/ directory.

Buildsystem changes

Support for relative libexec dir.

Frameworkintegration

the file dialog now remembers its size correctly, and works better with remote URLs.

Getting started

On Linux, using packages for your favorite distribution is the recommended way to get access to KDE Frameworks.

Building from source is possible using the basic cmake .; make; make install commands. For a single Tier 1 framework, this is often the easiest solution. People interested in contributing to frameworks or tracking progress in development of the entire set are encouraged to use kdesrc-build

Frameworks 5.2.0 requires Qt 5.2. It is part of a series of planned monthly releases making improvements available to developers in a quick and predictable manner.

A detailed listing of all Frameworks and other third party Qt libraries is at inqlude.org, the curated archive of Qt libraries. A complete list with API documentation is on api.kde.org.

Contribute

Those interested in following and contributing to the development of Frameworks can check out the git repositories, follow the discussions on the KDE Frameworks Development mailing list and contribute patches through review board. Policies and the current state of the project and plans are available at the Frameworks wiki. Real-time discussions take place on the #kde-devel IRC channel on freenode.net.

You can discuss and share ideas on this release in the comments section of the dot article.
