+This patch contains a breaking change for anyone setting the undocumented `rethrowAfterCapture` option for `@sentry/serverless`'s AWS wrapper to `false`, as its functionality has been removed. (That said, we couldn't find any projects in GitHub which do.) For backwards compatibility with anyone setting it to `true` (which is also the default), the option remains in the `WrapperOptions` type for now. It will be removed in the next major release, though, so we recommend removing it from your code.
