## `@deepgram/react` 0.2.0

`@deepgram/react` 0.2.0 adds runtime Voice Agent controls and makes React session lifecycle handling safer. The release updates the React layer for `@deepgram/agents` 0.1.2 and `@deepgram/sdk` 5.9.0.

### Runtime controls and notifications

Use `sendAgentMessage()` to inject an agent message with `"default"`, `"queue"`, or `"interrupt"` behavior. Use `updateListen()`, `updateThink()`, `updateSpeak()`, and `updatePrompt()` to change supported agent settings during a session.

The provider and standalone hook now expose typed callbacks for protocol notifications, including confirmations for each runtime settings update. `useAgentMode()` and `useDeepgramAgent()` also expose the `"thinking"` mode and `isThinking` state.

### Lifecycle and upgrade notes

Start, stop, reconnect, and React StrictMode handling now clean up canceled or failed microphone, playback, and client-tool resources. Automatic start failures call `onSdkError`, or `console.error` when no callback is set. A manual `start()` call rejects instead.

This is a `0.2.0` release. Update exhaustive `AgentMode` switches to handle `"thinking"`; public context and hook result types add required members; `registerClientTool()` returns an unsubscribe function; and `useDeepgramAgent().start()` starts a fresh session and clears `conversation`.

See [React Hooks & Provider](/docs/browser-agent-react) and the [migration guide](https://github.com/deepgram/react/blob/main/MIGRATION.md) for API details and upgrade examples.
