TLDR:
-
- Fragment Refs → stable
- use(browser()) to opt out of SSR
- RSCs can render
- Trusted Types support, useful alongside CSP to prevent XSS

In our latest RN headline, we caught an important RFC and dozens of WIP PRs to clarify the public C++ API
This follows the "Stable API" work already done on JS/TS/Java/Kotlin
