+## Updating `@sentry/serverless` exports
+
+The `AWSServices`, `GoogleCloudGrpc`, and `GoogleCloudHttp`. integrations have been removed from `@sentry/serverless` package. See the [table below](#deprecate-class-based-integrations) to find what to upgrade to.
+
+Using the `Sentry.AWSLambda` export has also changed. It no longer re-exports all of methods of the Node SDK, you'll have to import them directly from `@sentry/serverless`, instead it only exports `init`, `wrapHandler` and `tryPatchHandler`.
+
+```js
+import * as Sentry from '@sentry/serverless';

+// before
+Sentry.AWSLambda.captureException(...);
+
+// after
