.server.jsextension, Webpack/Vite unification...React Optimizing Compiler (React Forget) rewritten, seems to progress well.
the Offscreen API offering new very interesting capabilities (instant transitions ❤️️)

Airbnb’s Trip to Linaria
Airbnb explains how they went from Sass to react-with-styles and then Linaria. It is a no-runtime CSS-in-JS framework with static CSS extraction. They explain their choice, migration strategy, and give a positive feedback on the tool they contribute to.
React Aria - Date and Time Pickers for All
React Aria has just announced the release of Date and Time Picker components and hooks. As you can expect, there is a real focus on accessibility, flexibility and internationalization. We can feel that there is a lot of work behind these components from the Adobe teams.
Notes on maintaining an internal React component library
Gabe works on Walrus, Digital Ocean's internal React design system. He offers a very detailed feedback on the maintenance of a React design system over time. He shares interesting lessons on the human aspect as well as on the design of props, the encapsulation of components or the management of version upgrades.
Capture Phase Event Handling in React
We often use the "bubbling" phase of DOM events, but it is sometimes useful to use the "capture" phase which is not very well known. We can use for example onClickCapture with React.

The cost of convenience
An interesting reflection on frontend abstractions and their cost... Proposes an interesting mental model to differentiate a framework from a library (IoC - Hollywood principle - "Don't call us, we'll call you"). All this illustrated with some React examples.
