+### Important Changes
+
+- **feat(react): Add TanStack Router integration (#12095)**
+
+  This release adds instrumentation for TanStack router with a new `tanstackRouterBrowserTracingIntegration` in the
+  `@sentry/react` SDK:
+
+  ```javascript
+  import * as Sentry from '@sentry/react';
+  import { createRouter } from '@tanstack/react-router';
+
+  const router = createRouter({
+    // Your router options...
+  });
+
+  Sentry.init({
+    dsn: '___PUBLIC_DSN___',
+    integrations: [Sentry.tanstackRouterBrowserTracingIntegration(router)],
+    tracesSampleRate: 1.0,
+  });
+  ```
+
+### Other Changes
+
+- fix(nextjs): Do not hide `sourceMappingURL` comment on client when `nextConfig.productionBrowserSourceMaps: true` is
+  set (#12278)
+
+## 8.6.0
+
+### Important Changes
+
+- **feat(metrics): Add `timings` method to metrics (#12226)**
+
+  This introduces a new method, `metrics.timing()`, which can be used in two ways:
+
+  1. With a numeric value, to simplify creating a distribution metric. This will default to `second` as unit:
+
+  ```js
+  Sentry.metrics.timing('myMetric', 100);
+  ```
+
+  2. With a callback, which will wrap the duration of the callback. This can accept a sync or async callback. It will
+     create an inactive span around the callback and at the end emit a metric with the duration of the span in seconds:
+
+  ```js
+  const returnValue = Sentry.metrics.timing('myMetric', measureThisFunction);
+  ```
+
+- **feat(react): Add `Sentry.reactErrorHandler` (#12147)**
+
+  This PR introduces `Sentry.reactErrorHandler`, which you can use in React 19 as follows:
+
+  ```js
+  import * as Sentry from '@sentry/react';
+  import { hydrateRoot } from 'react-dom/client';
+
+  ReactDOM.hydrateRoot(
+    document.getElementById('root'),
+    <React.StrictMode>
+      <App />
+    </React.StrictMode>,
+    {
+      onUncaughtError: Sentry.reactErrorHandler(),
+      onCaughtError: Sentry.reactErrorHandler((error, errorInfo) => {
+        // optional callback if users want custom config.
+      }),
+    },
+  );
+  ```
+
+  For more details, take a look at [the PR](https://github.com/getsentry/sentry-javascript/pull/12147). Our
+  documentation will be updated soon!
