React 16.13.0 introduces bugfixes and new deprecation warnings to prepare for future releases. It includes warnings for state updates across components and for using conflicting CSS property rules, helping developers avoid common pitfalls.
React 16.13.0 has been released, featuring essential bugfixes and warnings aimed at developers. The update helps prepare users for an upcoming major release by addressing potential issues with application state and styling.
This release emphasizes that modifying the state of another component during render can lead to unintended side effects. A new warning will appear when developers attempt this, urging the use of useEffect for such scenarios. This aims to streamline debugging and ensure better component behavior.
React now warns developers when conflicting longhand and shorthand CSS properties are used. For example, mixing 'background' with 'backgroundColor' can yield unexpected results. The warning encourages developers to avoid such conflicts to ensure consistent styling.
String Refs, an older API type, is slated for deprecation. This version introduces pre-deprecation warnings for developers still using String Refs, especially in patterns like Render Props, where it could create confusion about component references. A future 'codemod' will assist in migrating away from this deprecated API.
