Great discussions again this month! We looked at the release of Vinext and what that means, and has a pretty long sidebar on how AI tooling is affecting the industry

TMiR 2025-12: Year in review, React2Shell (RCE, DOS, SCE, oh my)

We'll be going live in @reactiflux.com around 12:30 ET for December's "This Month in React" ( @tmir.reactiflux.com ), where Carl, Mo, and I will be breaking down the "React2Shell" RSC vulnerability - what happened, why, impact, and more. Also looking at the ecosystem and year in review.

Join us!

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.

A great technical analysis github.com/ejpir/CVE-20...

Critical Security Vulnerability in React Server Components – React The library for web and native user interfaces

There is critical vulnerability in React Server Components disclosed as CVE-2025-55182 that impacts React 19 and frameworks that use it.

A fix has been published in React versions 19.0.1, 19.1.2, and 19.2.1. We recommend upgrading immediately.

Celebrating the Launch of the React Foundation | OpenJS Foundation A New Era for React, and a Stronger JavaScript Ecosystem

New Era for React = Stronger JavaScript Ecosystem 💙

React doesn’t live in isolation - It works alongside Node.js, Electron, webpack, and more. A dedicated foundation under the Linux Foundation means more collaboration, security, and sustainability across the ecosystem.

How to enable Hermes v1: reactnative.dev/blog/2025/10...

Building off "static Hermes", avg improvement of 60% over current Hermes. Tested in the wild with Expensify, on high- and low-end devices

Hermes v1!

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

Y'all this is not a drill, there is a network panel!!! Genuine web parity tbh

"investing in performance" yada yada. Traces and flamegraphs are massive tho

Talk about DevTools. Perf panel!!!

This is the real keynote tbh. This is officially React Native Conf

Web performance APIs too???

New docs! reactnative.dev/docs/element...

We talked about this last August! Cool! www.reactiflux.com/transcripts/...

Web APIs new in 0.82???

"React Native is moving from being inspired by the web, to being aligned with it"

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.

Reactivated v4! Rewritten to take advantage of the new architecture. FlashList and Legend List too. React Native Enriched is the new rich text editor from Software Mansion
