Carl and I had plenty to say about the new releases this month... and then we had _more_ to say about topics like the state of the frontend education industry and what that means for devs!

Highly recommended episode. It feels like we're in the middle of a pivotal point for React. One more in React's long history, but I don't think we have seen conditions for disruption in the React ecosystem at this level before.

Researchers have found two new vulnerabilities in React Server Components while attempting to exploit the patches last week. These are new issues, separate from the critical CVE last week. The patch for React2Shell remains effective for the Remote Code Execution exploit.

New architecture shipped as default 1 year ago, October 2024. Stopped supporting old architecture in May 2025. Today, from 0.82, they're removing the old architecture completely!

"new architecture started in 2018" when's the last time you shipped something you worked on for > 5 years

Aha: DevTools are 0.83, planned for later this year. With the recent release cadence, I tend to believe them. DOM APIs are still pretty big, if they dropped all of this today at once I'd be a bit shocked

This is actually really big. This is what the new architecture enables, but the work has to be done before the new architecture can actually be taken advantage of.
