+## 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 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) - docs will
+ follow soon!
