grommet 2.0.0-beta.7 on Node.js Yarn

Breaking Changes

Moved to Styled Components v4 🎉
Internal DOM structure of Button changed. This might be a breaking change if you were using button.extend in the theme.
Button now has an explicit disabled prop, now not sending onClick will still enable the button.
Narrow has been removed as a breakpoint name (it is small now). Also, theme.edgeSize.narrow has been moved to theme.global.breakpoints.small.edgeSize. More here.
Checkbox theme structural changes (theme.checkBox):
- Moved radius from border to check
- Renamed check.width to check.thickness
- Moved check.color to the root checkBox entry since it affects both toggle and check instances
Normalized color inside theme:
- border-light and border-dark changed to border.light and border.dark
- theme.global.text.color moved to theme.global.colors.text
- theme.global.control.color moved to theme.global.colors.control
- If you don't set a theme.button.primary.color, primary buttons by default will use theme.global.colors.control instead of theme.global.colors.brand
- More here.
