LGTM, what about adding a CHANGELOG file now that we'll make a second release?

Added a second commit with the changelog and the release.

(!) Mixing named and default exports
https://rollupjs.org/guide/en/#output-exports
The following entry modules are using named and default exports together:
src/index.js

Consumers of your bundle will have to use chunk['default'] to access their default export, which > may not be what you want. Use output.exports: 'named' to disable this warning

Is this warning expected?

Thanks for spotting it, I didn't notice it in the output... it looks like that auto is not so smart in the end... :| Reverted it back to how was it before.

I also changed the release date in the changelog to today.
