Hi everyone!
This week, the community continued to publish React-related Agent skills. React RSCs and Next.js are hit by another set of DoS vulnerabilities, and it’s recommended to upgrade immediately.
The React Native side is more exciting, with Expo SDK 55 in beta and upcoming support for new CSS features. We now have 2 distinct libraries implementing home screen widgets, and need to understand the trade-offs of each approach.

Hi everyone!
This week, we saw a lot of activity on X about the new AI skills system. Personally, what excited me most is the new Firefox release that unlocks interesting things for React developers.
The React Native ecosystem is also super active, with many interesting releases. And I’m sure Expo 55 beta will drop just after we send our email 😅, so make sure to check their blog because it’s coming soon.

Hi everyone!
This week, it remains important for me to raise awareness about the React Server Components vulnerability, since an exploit is now widely available. Thankfully, we also have more positive React news!
It’s even hotter on the React Native side. We were patiently waiting for 0.83 to publish 😇 and it’s now out. You can now use <Activity> in React Native 🔥. Reanimated 4.2 is also out with Shared Elements Transition support 🔥.
It’s the survey season, don’t forget to answer the 2 most important ones that are currently open:

Hi everyone!
A major React 19 Server Functions vulnerability has just been disclosed. Make sure to upgrade your React 19 or meta-framework ASAP!
On the mobile side, we have more positive news: RNRepo should speed up our React Native builds even more, and Shared Elements Transitions are coming soon! (unlike React Native 1.0 😅)
Don’t forget to answer the State of React 2025 survey while it’s still open!

Hi everyone, Seb here! 👋
It's been another quiet week in the ecosystem, probably because everyone was afraid to announce anything during the massive Cloudflare outage! By the way, this one was not caused by useEffect 😆!
We have a good variety of interesting links, but I’m not sure what could be the headline. The most important news was probably the announcement of the upcoming CSS grid support in Yoga and React Native, but it’s still a draft PR for now. Also excited by the TC39 proposals progressing.
Make sure to take the State of React 2025 survey, which just opened today!

Hi everyone, Seb here! 👋
This week has been relatively calm in the ecosystem. We have a good variety of community blog posts, releases, and weak signals. I'm not sure what to highlight, so I'll just let you enjoy reading it!

Hi everyone, Seb and Armand here! 👋
This week, we found various interesting React releases and links about directives, Partial Pre-Rendering, performance, micro-frontends, i18n, among other things.
On the React Native side, we had 2 major releases and various interesting weak signals. Beware of the RN Dev Server vulnerability, and make sure to upgrade if needed.

Hi everyone!
This week we have a lot of interesting content about Next.js, with a new major release dropping just before their flagship conf. But also fair cricitisms showing that not everyone is satisfied with the framework.
On the mobile side, React Native developers will enjoy improved support for iOS 26 and the ability to provide native iOS header items. BottomTabs is now v1, and Solito v5 dropped with a paradigm change.
Let’s also welcome a new co-author of this newsletter: Armand Petit helped me on the React Native section.

Hi everyone!
This week is a big one: we barely had time to recover from last week's React 19.2 release, and now React Conf is happening live with another bunch of exclusive announcements!
I'll let you discover it all for yourselves below, enjoy!👌
