KDE has announced the release of KDE Frameworks 6.12.0, which comprises 72 addon libraries for Qt. These libraries offer a diverse range of essential functionalities, characterized by their maturity, peer-reviewed quality, and thorough testing, all accompanied by user-friendly licensing terms. The release encompasses bug fixes, enhancements, and refinements to various features. The latest versions feature Baloo, which prevents race conditions during updated file modification; Breeze Icons, which eliminates themed SmartGit icons; and introduces MIME-type icons for Kdenlive project files.

Extra CMake Modules now incorporate BSL-1.0 as GPL-compatible, enhance documentation for ECM QML modules, eliminate the conditional branch for CMake versions older than 2, and mandate CMake version 3.16 or higher for tests. KArchive has been updated to include KF7 TODOs and Kgzipfilter. In C++, nullptr is utilized in place of zero. KcalendarCore has received minor updates, while KCodecs has transitioned entity tables into read-only data sections. KConfigWidgets has been enhanced to KRecentFilesAction, and KCodecs has relocated entities tables into read-only data sections.

KFileMetaData has been revised to utilize the non-deprecated QDomDocument::setContent overload, while Exiv2 has been transitioned to a new version of QDomDocument::setContent. The release encompasses enhancements to documentation, upgrades to the API, and minor bug fixes.

Here is the full announcement:

Installing binary packages

On Linux, using packages for your favorite distribution is the recommended way to get access to KDE Frameworks.  Get KDE Software on Your Linux Distro wiki page

Compiling from sources

The complete source code for KDE Frameworks 6.12.0 may be  freely downloaded. Instructions on compiling and installing are available from the  KDE Frameworks 6.12.0 Info Page.

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 6.12.0 requires Qt 6.5.0.

A detailed listing of all Frameworks with API documentation is on  api.kde.org.
