npm install --save styled-components@beta

• Add warning when component is not a styled component and cannot be referred via component selector, by @egdbear (see #2070)

• Fix how ampersand is handled in self-referential selector combinations, e.g. & + & (see #2071)

• Add babel macro for full-featured interop with create react app v2+, by @lucleray (see #2032)

  When using CRA v2, import styled components from styled-components/macro instead to gain all the benefits of our babel plugin.

• Add a warning when wrapping a React component with styled() and the className isn't used (meaning styling isn't applied), by @Fer0x (see #2073)
