Breaking Changes

ReactJS 16 breaking changes

Source: https://reactjs.org/blog/2017/09/26/react-v16.0.html#breaking-changes

Breakage	Migration path
Errors in the render and lifecycle methods now unmount the component tree by default.	To prevent this, add error boundaries to the appropriate places in the UI.This can be done easily via the OverReact ErrorBoundary utility component.
Unitless props.style string values are no longer auto-converted to px.This has been a warning since React 15.0.0.	Change values from Strings to nums, or add a unit explicitly to string
react_dom.render calls within React lifecycle methods are no longer guaranteed to be synchronous, and may return null	Either: Use Portals to render content in a different DOM treeUpdate code to handle async mounting
setState callbacks (second argument) now fire immediately after componentDidMount / componentDidUpdate instead of after all components have rendered.	Transfer callback logic into componentDidUpdate.
It is not safe to re-render into a container that was modified by something other than React. This worked previously in some cases but was never supported. We now emit a warning in this case.	Instead you should clean up your component trees using unmountComponentAtNode.
Bool values used in non-bool props are no longer stringified, and are ignored. In most cases, passing bool values to these props is a programmer error, and should be replaced with the correct attribute values.	.toString() the value in any places where "false" or "true" are needed.
Previously, changing the ref to a component would always detach the ref before that component’s render is called. Now, we change the ref later, when applying the changes to the DOM.	Should not affect most usages.
When replacing <A /> with <B />, B.componentWillMount now always happens before A.componentWillUnmount. Previously, A.componentWillUnmount could fire first in some cases.	Should not affect most usages. If it does, switching from componentWillMount to componentDidMount should resolve the issue, and will be functionally equivalent in most cases.

Dart API breaking changes

Breakage	Migration path
The react_server.dart entrypoint has been removed	None
The react_test.dart entrypoint has been removed	None
Component.bind is removed	Set up event handler manually.
react_test_utils.SimulateNative is removed	Use react_test_utils.Simulate instead.
jsify is removed from js_interop_helpers.dart	Use dart:js, and replace jsify with JsObject.jsify.
getProperty / setProperty are removed from js_interop_helpers.dart	Use the same functions from dart:js instead.
ReactComponentFactory is removed	Use ReactComponentFactoryProxy instead.
emptyJsMap is removed	Use newObject() from dart:js_util instead.
EmptyObject is removed	Use the class instance created by calling newObject() from dart:js_util instead.
ReactComponent.isMounted is removed	Set up your own flags using component lifecycle methods.

Actually, wait, I want to double check that there aren't any breakages in 5.1.0 that should have made it into 5.0.0
