Do you want to request a feature or report a bug? Bug What is the current behavior? In React 16, a text input with a value and autofocus will set the cursor at the _end_ of the input. `` If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem. Your bug will get fixed much faster if we can run your code and it doesn't have dependencies other than React. Paste the link to your JSFiddle (https://jsfiddle.net/Luktwrdm/) or CodeSandbox (https://codesandbox.io/s/new) example below: See the React 16 repro here: https://codepen.io/matthewg0/pen/XymjYo What is the expected behavior?

Summary Adds an official opt-out mechanism to suppress the "Download the React DevTools for a better development experience" console message. Fixes #24283. Approach The fix introduces a property on the pre-existing object. When set to before React loads: 1. The DevTools download prompt in / is skipped via a new guard. 2. A bare placeholder hook with only does not trigger the legacy "DevTools too old" warning in — the reconciler recognizes it as an intentional suppression flag, not an unsupported hook. 3. Real hooks that set still inject and function normally. This avoids the brittle workaround of fully overriding which can break DevTools entirely. Usage Place this before any React script on the page.
