Our Commentary ​

View Transitions in React is a big deal. We've been waiting for this native integration. It's going to make complex UI animations so much easier to implement without reaching for external libraries. I'm genuinely excited to see how this changes the feel of single-page applications. Fragment Refs are a nice quality-of-life improvement too. And Trusted Types? That's just good hygiene. It's a solid release.
