2.0.0 (2018-06-14)

New Features

Improved TypeScript Definitions
New FlowTyped Definitions
Improved TS and Flow integration
Documentation re-organization to make it easier to identify the most common props.
A new prop getter called getMenuProps is recommended for accessibility purposes.
Simplified setting element IDs with new props: labelId, inputId, menuId, and getItemId which simplifies the internal implementation as well as resolving confusing accessibility issues. (These props are not required).

getButtonProps was renamed to getToggleButtonProps
A bunch of accessibility-related improvements and fixes
Downshift now works much better with menus rendered within a portal (given you use the new getMenuProps()).

Previously we supported render (<Downshift render={() => {}} />) and children (<Downshift>={() => {}}</Downshift>). Now we only support the children prop.

-<Downshift render={yourRenderFn} />
+<Downshift>{yourRenderFn}</Downshift>

The breakingChanges prop has been removed and the resetInputOnSelection option is now the default behavior. It only applies for use cases where the selectedItem is controlled. Learn more about this in #243.
If you're using CommonJS, you'll need to change your require statement:

-const Downshift = require('downshift')
+const Downshift = require('downshift').default

If you're using resetIdCounter, that's now exported separate from Downshift:

-import Downshift from 'downshift'
-Downshift.resetIdCounter()
+import Downshift, {resetIdCounter} from 'downshift'
+resetIdCounter()

All of the project contributors have been awesome. Thank you all. Here are a few specific people who helped in this release:
