Breaking Changes - Core

Beta Give feedback

1. Remove separators prop from FlexLayout
2. Simplify Spinner #1335
   +0
3. Card interactive prop
4. Default style injection to false Make static CSS file / disable style injection the default #2532
5. Navigation Item: Remove wrapping <div/> so that NavigationItem renders either a <button\> or <anchor/>, this will enable us to pass ...rest to the actual <button\> or <anchor/>, rather than to the wrapping <div/>. The breaking change is the Typescript types and the ref, which currently a <div/> . This change is now possible due to us adding a more customisable API through the render prop. add render prop to NavigationItem (#3279) #3417
6. Remove UNSTABLE_ backwards compatibility
7. ViewportProvider Alternative responsive props #3265
8. Use of @media (hover: hover)
9. Formalize --saltComponent-xyz API (vs --componet-xyz)
10. Investigate potential inclusion mentioning CSS layer, depends on whether minimum browser support can be bumped?

I'd suggest removing the responsive behaviour that's built into layout components when we're doing V2. Alternative could be the spike I did on responsive props where consumers can wrap any component to make it responsive.
