browser() is a new API for components that depend on the browser. Calling use(browser()) suspends during server rendering, so React can show the nearest Suspense fallback and continue rendering the component on the client. react.dev/reference/react-do…

trusted types support helps, but third party scripts still break enforcement during rollout

If the new React release doesn’t get more hype than GPT-6 Astra, I’m officially declaring coding solved.

Learn from angular teams, they've added agents md while installing angular plus they won't get hacked regularly. The react gets hacks more than stable updates.

Context in Server Components is the one I've been waiting for — passing config down without prop-drilling through every layout boundary. View Transitions going stable is huge too, that's been the biggest gap versus what you could hack together with a router-level library.

Who cares, I vibe coded my own framework, and holy shit, the agents are so good at it already! 😂 webjs.dev Fun aside, I still love React. Congrats on the release!

Stabilizing View Transitions and Fragment Refs together is a meaningful step for complex UI flows. The combination should let apps express coordinated updates without turning every transition into framework-specific plumbing.

React 19.3 making View Transitions and Fragment Refs stable, while adding browser() and Trusted Types support, is a concrete step toward safer, more capable UI primitives.

View Transitions becoming stable is a big deal. Curious how much this will change the way we build animations in React.

React 19.3 just dropped? Finally, stable transitions & refs—time to upgrade or die.

Trusted Types is the quiet one for anyone rendering other people's HTML. We already run email bodies through DOMPurify into a sandboxed iframe; React cooperating with require-trusted-types-for means the CSP can enforce that path instead of trusting us to remember it.

稳定版对生产团队很重要，尤其是和 Suspense、服务端组件组合时，迁移边界要有清晰的回退方案。
