Bug

What is the current behavior?
For buttons with children other than text nodes, when the disabled attribute is true, click handlers are still triggered

If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem via https://jsfiddle.net or similar (template: https://jsfiddle.net/reactjs/69z2wepo/).
load code pen and check react v 15.4.0, observe button click behaviour for both instances

What is the expected behavior?
button click should not trigger on click handler

Which versions of React, and which browser / OS are affected by this issue? Did this work in previous versions of React?
bug appears in v15.4.0
behaviour is correct in v15.3.1

Thanks for the report @krisyoung. This issue was resolved with the 15.4.1 release. The PR that fixed this was #8387. Here's a Codepen running the latest release (15.4.2) showing that the issue no longer occurs. You should be able to safely update from 15.4.0 to 15.4.2 since there were only patch releases!

Hope that helps.

Thanks, my bad for not checking there was a 15.4.x
