This pull request is fully signed and it will be integrated in one of the next CMSSW_13_2_X IBs (tests are also fine) and once validation in the development release cycle CMSSW_14_0_X is complete. This pull request will be automatically merged.

Dear @antoniovilela,

Can I ask a new release so that we can produce a relval MC sample using CSMSW_13_2_X with the implemented PR. We are waiting for it to produce MC described in this JIRA ticket (PDMVRELVALS-223)

Thank you,
Saeahram
