• Let test both the master version and this 12_4_X backport in the IB at the same time. If tomorrow there are no issues from both them, we can start building the CMSSW_12_4_X release with this vertex smearing scenario for the MC production.

[cmsbuild]

This pull request is fully signed and it will be integrated in one of the next CMSSW_12_4_X IBs (tests are also fine) and once validation in the development release cycle CMSSW_12_5_X is complete. This pull request will be automatically merged.
