---------------------
|
||||
|
||||
### Component
|
||||
- Feature: `input` is now multi-line.
|
||||
- Feature: `input` style can now be customized.
|
||||
- Feature: Support `ResizableSplit` with customizable separator.
|
||||
- Breaking: MenuDirection enum is renamed Direction
|
||||
- Fix: Remove useless new line when using an alternative screen.

|
||||
### Dom
|
||||
- Feature: Add the dashed style for border and separator.
|
||||
- Feature: Add colored borders.
|
||||
- Feature: Customize with gradient color effect. Add the following decorators:
|
||||
- `colorgrad`
|
||||
- `bgcolorgrad`
|
||||
- Feature: Add `LinearGradient`!
|
||||
- Improvement: Color::Interpolate() uses gamma correction.
