Hi React developers! Has anyone started experimenting with React 19 beta? I'm particularly excited about the improvements to concurrent rendering and the new Server Actions feature. The automatic batching improvements look promising for performance. I've tested the new use() hook for data fetching and it simplifies a lot of async logic. What are your thoughts on the breaking changes? Is migration going to be smooth from React 18?
