## \[3.4.0] - Mar 9, 2026

[#340---mar-9-2026](docId\:ITj6oq0l4yz8s6fAo-y5k)

### New Features

[#new-features](docId\:ITj6oq0l4yz8s6fAo-y5k)

- Add a server-safe bundle that is automatically resolved when imported in React Server Components, excluding client-only React APIs ([#318](https://github.com/optimizely/react-sdk/pull/318))
- Add `qualifiedSegments` prop to `OptimizelyProvider` for passing pre-fetched ODP segments, enabling synchronous ODP-based decisions during SSR ([#318](https://github.com/optimizely/react-sdk/pull/318))
- Add `getQualifiedSegments` utility for fetching ODP audience segments server-side ([#318](https://github.com/optimizely/react-sdk/pull/318))

### Enhancements

[#enhancements](docId\:ITj6oq0l4yz8s6fAo-y5k)

- Improve `useExperiment`, `useFeature`, and `useDecision` hooks to compute decisions when config and user context (including segments) are available, without waiting for `onReady` ([#318](https://github.com/optimizely/react-sdk/pull/318))
- Add comprehensive server-side rendering integration guide covering SSR, SSG, and App Router patterns ([#318](https://github.com/optimizely/react-sdk/pull/318))
