This release sees the introduction of a brand new core based on systemjs-hmr and brings support for SystemJS 0.20.
A large amount of effort went into making the API backwards compatible with the old version and you should be able to upgrade without any code changes, with the exception of how the library is imported.
Expect more exciting features in the near future, including syntax error overlays in browser and NodeJS support.
systemjs-hot-reloader now acts as the client for systemjs-tools and the old client has been removed.
Enjoy 🎉🎉🎉
