Krita 5.2.3 is released after several weeks of testing of the beta. This is a bugfix release that primarily brings a complete overhaul of our build system, making it so that our CI system can now build for all 4 platforms (a Continuous Integration system basically builds a program after every change, runs some tests, and based on that helps us track down mistakes we made when changing Krita's code).

Beyond the rework of the build system, this release also has numerous fixes, particularly with regard to animated transform masks, jpeg-xl support, shortcut handling on Windows, and painting assistants.

In addition to the core team, special thanks go out to Freya Lupen, Grum 999, Mathias Wein, Nabil Maghfur Usman, Alvin Wong, Deif Lou, Maciej Jesionowski, and Rasyuqa A. H. for various fixes, as well as the first time contributors in this release cycle (Each mentioned after their contribution).
