Our Commentary ​

SolidJS 2.0 is shaping up to be a robust release. The deprecation of server-side setter writes is a strong move towards purity, which I appreciate for predictable SSR. The SSR hydration fixes for async generators are also crucial; those kinds of subtle bugs can be a nightmare to track down. It's good to see the core framework getting these foundational improvements.
