Highlights of Krita 4.4 include:
- Multi-threading for fill layers to yield a lot faster performance.
- Support for patterns of fill layers and new screentone options for the fill layer. There is also a multigrid fill layer feature for penrose tilings.
- Support for Disney Animation's SeExpr expression language that is basically used as a tiny shader language for fill layers.
- Various brush engine improvements.
