SystemJS 0.21.0

This release represents a new build of the 6KB SystemJS production loader with the following changes:

• Support for loading modules as AMD falling back to global detection (#1778)
• AMD modules are treated as having the shape { default: module } through System.import instead of returning the default directly (this will ensure dynamic import workflows work out correctly) (#1786)

Now that Rollup supports the system module format and code splitting, this will allow easy production workflows against chunking and CDN externals.
