Easy way to block the user from interacting with your UI.
Add rollup to generate es modules Remove deps, now 8k (5k min) Use CSS animations for default loader (use your own loader for older IE support) New: message prop to add message which appears above the loader. Break: Loader is no longer exposed (you can access still it from lib) Break: reduxMiddleware is now in react-block-ui/reduxMiddleware as default export
