React v19 – React
Starting in React 19, you can now access ref as a prop for function components: ... New function components will no longer need forwardRef, and we will be publishing a codemod to automatically update your components to use the new ref prop. In future versions we will deprecate and remove forwardRef. refs passed to classes are not passed as props since they reference the component instance. We also improved error reporting for hydration errors in react-dom.

React 19 Release underwhelming or just me?
Lol, man if you want an "overwhelming" release, head over to Svelte, they are still fighting a civil war over the version 5 release. Or Vue, they still haven't gotten over the version 2 to version 3 transition. React is mature, stable, and boring. Those are the quality that gets the job done. More on reddit.com

February 3, 2025React 19 is officially out!
I just love how they introduce new terms and features and give very obvious names so everything is clear from the get go and there will be absolutely no problems with communication /s. For example, what is "action" in context of react? Is it something you pass into "dispatch" function ? Or maybe it is for submission action? Or, possibly it is something to update part of the UI in background ? Or maybe it is a form submission action that is roughly equialent to action attribute ? In my opinion react becomes more and more complex and hard to get into. It is also, IMO, more focused on fixing problems react itself introduces, instead of solving problems of developers (although they sometimes overlap). I will not be surprised that in React 20 they will focus primarily on fixing complexities of React 19. More on reddit.com

r/reactjs on Reddit: React 19 Release underwhelming or just me?
February 3, 2025 -
I’ve been using React 19 for a good month now and testing out some of the features. I’ve used it with NextJS and in a separate SPA app.
Is it me or does the release feel very underwhelming? Is there something I’m missing and others have been finding it much better than before?
Maybe I expected much more given the long gap between v18 and v19. V19 definitely an improvement but it doesn’t feel like it moved the needle much.

I am not underwhelmed because I don't want or expect the wheel to be reinvented every year, and I am excited about the future of server components. I am happy that work is continuously being done to make React faster, more reliable and offer new concepts without introducing breaking changes.

React 19 : New Features and Updates - GeeksforGeeks
February 27, 2026 - Improved Stylesheet Management: React 19 takes control of stylesheet loading and insertion order within the DOM. This eliminates potential issues with styles being applied before components are rendered. Declarative Control: You can specify stylesheet dependencies directly within your components, making it easier to manage styles that are specific to a particular component or group of components. Reduced Boilerplate: React handles the complexities of stylesheet management, reducing the need for manual workarounds or complex styling libraries.

Overall, good release. Lots of good quality of life improvements. The Suspense Data-Fetching drama that happened a few months ago was handled very well by the React team, and their solution is honestly a best-of-both-world solution that pleases everyone. I feel like Transitions and Suspense need more documentation. It's clearly what the React team is interested in exploring, and it's great to use, but the documentation is really lacking and the timing details seem to change with every major release. The lack of documentation and education surrounding those features contribute to the feeling that React is starting to get "bloated" or "needlessly complex".

Support for Custom Elements: React 19 now passes all tests on Custom Elements Everywhere. StrictMode changes: useMemo and useCallback will now reuse the memoized results from the first render, during the second render. Additionally, StrictMode will now double-invoke ref callback functions on initial mount. UMD builds removed: To load React 19 with a script tag, we recommend using an ESM-based CDN such as esm.sh.
