Hello! The `0.19` release is about internal fixes, optimizations and refactoring, as well as some work on PRs that we’ll hopefully tell you about soon!

## Jest tests

Thanks to our contributer, [@richardwillars](https://github.com/richardwillars), and following the example set by Uppy Server, we’ve [switched to Jest](https://github.com/transloadit/uppy/pull/310) for Uppy’s unit tests, and added a bunch of new tests as well. And even more are being [added](https://github.com/transloadit/uppy/pull/346) as we speak!

We're also happy to report that [more tests](https://github.com/transloadit/uppy-server/compare/3341a9592d0723fd9b58ec77d8c762f20b434704...d3c6f5b409d08f588d1704b77181e5c0342ca322) have been added for Uppy Server.

## Dashboard APIs

We’ve exposed `show/hide/isOpen` APIs for the Dashboard UI plugin. Now you can open and close the modal dialog programmatically:

```js
var modal = uppy.getPlugin('Dashboard')
modal.show()

...

button.addEventListener('click', () => {
  if (modal.isOpen()) {
    modal.hide()
  } else {
    modal.show()
  }
})
```

Check out [the docs](https://uppy.io/docs/dashboard/#Methods).

Informer supports “explanations”, a questionmark (?) button that shows more info on hover / click.
