- Split the google-noto-cjk-fonts package into google-noto-sans-cjk-fonts and google-noto-serif-cjk-fonts, and provide the variable fonts in google-noto-sans-cjk-vf-fonts and google-noto-serif-cjk-vf-fonts.
- Drop several sub packages which are not installed by default from the google-noto-cjk-fonts package.
- Like google-noto-sans-cjk-*-fonts, google-noto-sans-*-fonts, google-noto-sans-mono-cjk-*-fonts, google-noto-serif-cjk-*-fonts and google-noto-serif-*-fonts
- Install the Noto CJK Variable Fonts by default.
