KDE has announced 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.

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.
