+# Migration Guide
+
+## 0.1 to 0.2
+
+`@deepgram/react` 0.2.0 adds runtime Voice Agent controls and updates the package for `@deepgram/agents` 0.1.2 and `@deepgram/sdk` 5.9.0.
+
+Install the new release:
+
+```bash
+npm install @deepgram/react@^0.2.0
+```
+
+### Handle the `thinking` mode
+
+`AgentMode` now includes `"thinking"`. Update exhaustive mode switches and any mode-to-label maps.
+
+```ts
+switch (mode) {
+  case "idle":
+  case "listening":
+  case "thinking":
+  case "speaking":
+    break;
+}
+```
+
+### Update typed context and hook wrappers
+
+`AgentContextValue` and hook result types now include required members for the new controls and state. Components that consume the hooks do not need a source change, but typed mocks, wrappers, and objects that implement these interfaces must provide the new members.
+
+### Keep the client-tool unsubscribe function
+
+`registerClientTool()` now returns an unsubscribe function. Existing calls that ignore its return value still work. Store and call the result when registering outside a component lifecycle:
+
+```tsx
+import { useAgentContext } from "@deepgram/react";
+
+function MapControls() {
+  const { registerClientTool } = useAgentContext();
+  const unregister = registerClientTool("get_location", () => {
+    return JSON.stringify({ latitude: 0, longitude: 0 });
+  });
+
+  // Later, when the handler is no longer needed:
+  unregister();
+}
+```
+
+`useAgentClientTool()` remains the preferred option inside React components and unregisters automatically on unmount.
+
+### Treat standalone `start()` as a fresh session
+
+`useDeepgramAgent().start()` now clears `conversation` before connecting. Keep any transcript that must survive a restart outside the hook, or restore it after the new session starts.
+
+Manual `start()` calls reject on failure. Handle the returned promise:
+
+```tsx
+import { useAgentControls } from "@deepgram/react";
+
+function ConnectButton() {
+  const { start } = useAgentControls();
+
+  async function handleStart() {
+    try {
+      await start();
+    } catch (error) {
+      console.error("Failed to start the Voice Agent", error);
+    }
+  }
+
+  return <button onClick={handleStart}>Connect</button>;
+}
+```
+
+Automatic start failures, including microphone failures during auto-start and reconnect, call `onSdkError` when it is provided.
+
+### Use the new runtime controls
+
+Use the controls from `useAgentControls()`, `useAgentConversation()`, or `useDeepgramAgent()` to update a connected agent without recreating the provider:
+
+```tsx
+import { useAgentControls } from "@deepgram/react";
+
+function TakeoverButton() {
+  const { sendAgentMessage, updatePrompt } = useAgentControls();
+
+  function takeOver() {
+    updatePrompt("Keep responses concise.");
+    sendAgentMessage("I will take it from here.", "interrupt");
+  }
+
+  return <button onClick={takeOver}>Take over</button>;
+}
+```
+
+Use `onListenUpdated`, `onPromptUpdated`, `onSpeakUpdated`, and `onThinkUpdated` on `AgentProvider` or `useDeepgramAgent()` to observe the matching server confirmation.
+
+See the [package README](packages/react/README.md) for the complete API surface.

 # Changelog
 
+## [0.2.0](https://github.com/deepgram/react/compare/react-v0.1.0...react-v0.2.0) (2026-09-10)
+
+
+### ⚠ BREAKING CHANGES
+
+* **react:** `AgentMode` now includes `"thinking"`.
+* **react:** Public context and hook result types add required members for the new agent controls and state.
+* **react:** `registerClientTool()` now returns an unsubscribe function.
+* **react:** `useDeepgramAgent().start()` begins a fresh session and clears `conversation`.
+
+### Features
+
+* **react:** Add `"thinking"` mode and `isThinking` state.
+* **react:** Add `sendAgentMessage()` with `"default"`, `"queue"`, and `"interrupt"` behavior.
+* **react:** Add `updateListen()`, `updateThink()`, `updateSpeak()`, and `updatePrompt()` for runtime agent settings changes.
+* **react:** Add typed callbacks for protocol notifications, including settings update confirmations.
+* **react:** Expose the new controls and state through `AgentProvider`, focused hooks, and `useDeepgramAgent`.
+
+
+### Bug Fixes
+
+* **react:** Harden starts, stops, reconnects, and StrictMode replay so canceled or failed sessions cannot retain stale microphone, playback, or client-tool resources.
+* **react:** Report automatic start failures, including microphone failures during auto-start and reconnect, through `onSdkError` or `console.error` when no callback is set. Manual `start()` rejects instead.
+* **react:** Publish portable declarations that resolve agent types from `@deepgram/agents` in consumer projects.
