Important Changes

• nextjs: Add Turbopack support for React component name annotation

  We added experimental support for React component name annotation in Turbopack builds. When enabled, JSX elements
  are annotated with data-sentry-component, data-sentry-element, and data-sentry-source-file attributes at build
  time. This enables searching Replays by component name, seeing component names in breadcrumbs, and performance
  monitoring — previously only available with webpack builds.

  This feature requires Next.js 16+ and is currently behind an experimental flag:

  // next.config.ts
  import { withSentryConfig } from '@sentry/nextjs';
  
  export default withSentryConfig(nextConfig, {
    _experimental: {
      turbopackReactComponentAnnotation: {
        enabled: true,
        ignoredComponents: ['Header', 'Footer'], // optional
      },
    },
  });

• hono: Instrument middlewares app.use()

  Hono middleware registered via app.use() is now automatically instrumented, creating spans for each middleware invocation.
