componentWillMount
componentWillReceiveProps

Hi there,
any idea when latest fixes around this will be released? I'm having warnings on v2.6.2 with React v16.9

Warning: componentWillReceiveProps has been renamed, and is not recommended for use. See https://fb.me/react-async-component-lifecycle-hooks for details.

* Move data fetching code or side effects to componentDidUpdate.
* If you're updating state whenever props change, refactor your code to use memoization techniques or move it to static getDerivedStateFromProps. Learn more at: https://fb.me/react-derived-state
* Rename componentWillReceiveProps to UNSAFE_componentWillReceiveProps to suppress this warning in non-strict mode. In React 17.x, only the UNSAFE_ name will work. To rename all deprecated lifecycles to their new names, you can run `npx react-codemod rename-unsafe-lifecycles` in your project source folder.

Please update the following components: DragSource(NodeRendererDefault), DropTarget(TreeNode)

Thanks!

@TdyP is this still happening for you? I haven't tried converting my implementation yet to hooks.
