<Summary type="rolling" window-days="90" release-count="50">
The SDK shipped three major versions in quick succession, fundamentally reshaping the API surface. In late March, `@elevenlabs/client` and `@elevenlabs/react` introduced breaking changes: the `Input` class disappeared in favor of methods like `getInputByteFrequencyData()` and `setMicMuted()` on the conversation object, while `useConversation` now requires a `ConversationProvider` ancestor and exposes granular hooks (`useConversationControls`, `useConversationStatus`, etc.) instead of a monolithic return shape. `@elevenlabs/react-native` underwent a complete rewrite, ditching its custom LiveKit-based provider to re-export the React package's API, with side-effects on import to polyfill WebRTC and configure native audio. After stabilization in early April, the SDK focused on multimodal and feature refinement: `sendMultimodalMessage` surfaced in hook controls, tool response mocking landed in the client, and the widget gained intelligent language auto-selection from localStorage and browser preferences. A late-April fix addressed Node.js ESM compatibility by switching to explicit `.js` file extensions in imports.
</Summary>

<Summary type="monthly" period="March 2026" release-count="37">
March delivered two major API overhauls. Early in the month, guardrail detection arrived via `onGuardrailTriggered` callback and type discriminants for `TextConversation` and `VoiceConversation`, letting developers distinguish conversation modes at compile time. Mid-month, v1.0.0 releases rewrote the React and React Native packages: `useConversation` now requires `ConversationProvider` context, the `Input` class was removed in favor of conversation methods like `getInputByteFrequencyData()` and `setMicMuted()`, and `@elevenlabs/react` now re-exports all of `@elevenlabs/client` to unify the surface. By month-end, tool response mocking shipped in the client, enabling agents to validate integrations without live backend calls.

<Release version="@elevenlabs/react-native@1.1.0" date="April 10, 2026" published="2026-04-10T14:05:38.000Z" url="https://github.com/elevenlabs/packages/releases/tag/%40elevenlabs/react-native%401.1.0">
### Minor Changes

-   0d5c368: Fix getInputVolume/getOutputVolume returning 0 in React Native by adding native volume providers using LiveKit's RMS and multiband FFT processors.

    **Breaking:** `getByteFrequencyData()` now returns data focused on the human voice range (100-8000 Hz) instead of the full spectrum (0 to sampleRate/2). On web, `getVolume()` is also computed from this range. The deprecated `getAnalyser()` method still provides direct access to the raw `AnalyserNode` for consumers needing full-spectrum data.

### Patch Changes

-   806edd0: Fix `startSession` errors being swallowed instead of surfaced via `onError` in `ConversationProvider`. Previously, when `Conversation.startSession()` rejected (e.g. "agent not found"), the UI would get stuck in "connecting" with no error feedback.

### Patch Changes

-   50ea6ef: fix: use explicit .js extensions in ESM imports for Node.js compatibility

    Switch `moduleResolution` from `bundler` to `nodenext` and add `.js` extensions to all relative imports. The published packages use `"type": "module"` but the compiled output had extensionless imports, which breaks Node.js ESM resolution. Also add `"type": "module"` to `@elevenlabs/types`.
