          This is an automated release PR for the patched version of `${{ inputs.version }}`.

          Upstream changelog: https://github.com/aptos-labs/aptos-core/releases/tag/${{ inputs.version }}

          On merge, this will trigger the [release publish workflow](${{ github.server_url }}/${{ github.repository }}/actions/workflows/aptos-light-client-patch-release-publish.yml), which will upload a new GitHub release with tag `{{ inputs.version }}-patched`.
