11.12.0

Important Changes

• feat(bundler-plugins): Enable hidden source maps and remove them after upload (#25637, #25645, #25646, #25647, #25648)

  The Sentry Rollup, Vite, webpack and esbuild plugins now turn on hidden source maps when your bundler has no source maps enabled and the plugin can upload them. They upload the maps to Sentry and remove them from the build output. You no longer need to set sourcemap: 'hidden' or filesToDeleteAfterUpload globs:

  sentryVitePlugin({ org, project, authToken });

  The new sourcemaps.deleteSourcemapsAfterUpload option controls the removal:

  • Unset: the plugin removes only the source maps it turned on itself. Source maps you enabled yourself stay in the build output, as before.
  • true: the plugin also removes source maps you enabled yourself, and switches visible source maps to hidden. Set this if you already use sourcemap: 'hidden' and want to drop your filesToDeleteAfterUpload globs.
  • false: the plugin never removes source maps.

  Builds in development mode or without an auth token, org and project do not change.

• feat(cloudflare): Propagate tracing context through Queue messages (#25306)

  Cloudflare Queue consumers can now link to the traces of the producers that sent the messages. Set queueTracePropagationBindings to the producer bindings that should add trace data to plain-object message bodies. Consumers remove this data before your handler runs, and the queue.process span links to every producer in the batch.

  export default Sentry.withSentry(
    env => ({
      dsn: env.SENTRY_DSN,
      queueTracePropagationBindings: ['BILLING_QUEUE', /^JOBS_/],
    }),
    handler,
  );

• feat(core): Answer managed tunnel requests in the runtime (#25997, #25998, #25999, #26000, #26001)

  serveTunnelIntegration() now answers tunnel requests before they reach your app, in Node.js, Bun, Deno, Cloudflare Workers and AWS Lambda. You no longer need a framework integration or a route handler, so any server setup works with only the integration:

  Sentry.init({ dsn, integrations: [Sentry.serveTunnelIntegration()] });

  To answer tunnel requests from your own code, set serveTunnelIntegration({ intercept: false }) and call handleTunnelRequestIfMatched.
