 #### New Features
 
 - A new [`prerelease`](https://github.com/slsa-framework/slsa-github-generator/blob/v1.6.0/internal/builders/generic/README.md#workflow-inputs) input was added to allow users to create releases marked as prerelease when `upload-assets` is set to `true`.
+- A new output `go-provenance-name` added which can be used to retrieve the name of the provenance file generated by the builder.
