### Breaking Changes

* `transform` now returns an object ([#244]). You now should write
  `transform(...).code` instead of just `transform(...)`. `code` is the only
  property for now, but this allows Sucrase to return source maps and possibly
  other values.
* The package's `dist` folder has been restructured, so direct internal module
  imports may break.

### Other changes

* Overhaul build system to use Sucrase for everything ([#243])
* Omit import helpers when unused ([#237]) (Alec Larson)
* Fix files accidentally included in final package ([#233])
* Various refactors and performance improvements.

# 2.2.0 (2018-05-19)

* Add support for JSX fragment syntax.
* Add support for custom JSX pragmas rather than defaulting to
  `React.createElement` and `React.Fragment`.
