Free raster graphics editor Krita 4.2.0 released with many improvements

Krita, The free open source painting program has been updated to version 4.2.0. This new major release includes updated support for graphics tablets, scripting APIs for animation, support for HDR displays on Windows, and more.
Krita is targeted at the conceptual art, illustration, and visual effects industries. The application was developed using Qt 5 and KDE Frameworks 5 and can run on Linux, Windows and macOS.
The latest Krita 4.2.0 includes updated tablet support for Windows, Linux and macOS. This includes improved support for multi-monitor setups, more supported tablets and bug fixes. To this end, Qt has been patched and the patch has been included upstream, but until the Linux distribution receives this updated Qt5, it is recommended that you use the Krita AppImage binary, which includes this patched Qt.

Another important change in Krita 4.2.0 is support for HDR displays. This feature is only available on Windows 10 and allows viewing your HDR images in HDR on supported hardware.
