* `[PlutoLib]` Added the `@ConstantExpression` annotation
* `[PlutoLib]` The `RAID#getIDOf` method now returns `OptionalInt` to avoid NPEs
* `[PlutoLib]` The transitive dependency JOML is now provided by `PlutoLib` instead of `PlutoStatic`
* `[PlutoLib]` Created a simple Color API
* `[PlutoShader]` Added the 8-bit RGBA `Color` class as a counterpart to AWT's `Color` class
* `[PlutoShader]` Added the `RGBA` and `RGB` single precision float color objects
* `[PlutoShader]` Added the respective `IRGBA` and `IRGB` read-only interfaces
* `[PlutoShader]` Added the `HSBA` and `HSB` single precision float color objects
* `[PlutoShader]` Added methods to convert between HSBA, RGBA, HSB and RGB
* `[PlutoShader]` Added the `UniformRGBA` and `UniformRGB` shader uniform types
Awaiting implementation:
* `[PlutoLib]` Moved `cz.tefek.pluto.io.pluto.pp` to `cz.tefek.pluto.io.plutopackage`
* `[PlutoLib]` Completely reworked the module system
* `[PlutoLib]` Created a simple Color API
## 20.2.0.0-alpha.2
