Thanks for that @turadg - sorry I missed it in the release notes.

Out of curiosity - it was removed in #2108 because it appears to be unused. What was your use-case for it?

[turadg]

We have a Select component that wraps react-select. Looking at its history, we built it on a fork of react-select. In Oct 2016 we switched back to npm distro of react-select on 1.0.0-rc.2. Our handleInputKeyUp went from getting the input value from the DOM to getting it by getInputValue.

Thanks for the reply @turadg. Is your use case now covered by the handleInputKeyUp event?

[turadg]

That's our handler for onKeyUp event. To get it working again I just replaced .getInputValue() with .state.inputValue. So all good.
