Important Changes

• cloudflare: Add trace propagation for RPC method calls

  Trace context is now propagated across Cloudflare Workers RPC calls, connecting traces between Workers and Durable Objects.
  This feature is opt-in and requires setting enableRpcTracePropagation: true in your SDK configuration:

  // Worker
  export default Sentry.withSentry(
    env => ({
      dsn: env.SENTRY_DSN,
      enableRpcTracePropagation: true,
    }),
    handler,
  );
  
  // Durable Object
  export const MyDurableObject = Sentry.instrumentDurableObjectWithSentry(
    env => ({
      dsn: env.SENTRY_DSN,
      enableRpcTracePropagation: true,
    }),
    MyDurableObjectBase,
  );

• breaking

  hono: Change setup for @sentry/hono/node (init in external file)

  To improve Node.js instrumentation, the sentry() middleware exported from @sentry/hono/node no longer accepts configuration options.
  Instead, you must configure the SDK by calling Sentry.init() in a dedicated instrumentation file that runs before your application code (read more in the Hono SDK readme:

  // instrument.mjs (or instrument.ts)
  import * as Sentry from '@sentry/hono/node';
  
  Sentry.init({
    dsn: '__DSN__',
    tracesSampleRate: 1.0,
  });

• nitro: Add @sentry/nitro SDK

  A new @sentry/nitro package provides first-class Sentry support for Nitro applications, with HTTP handler and error instrumentation, middleware tracing, request isolation, and build-time source map uploading via withSentryConfig.
  Read more in the Nitro SDK docs and the Nitro SDK readme.
