• feat(react): Add TanStack Router integration (#​12095)

  This release adds instrumentation for TanStack router with a new tanstackRouterBrowserTracingIntegration in the
  @sentry/react SDK:

  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,
  });

  set (#​12278)

v8.6.0

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:

  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:

  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:

  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. Our
  documentation will be updated soon!
