This pull request is fully signed and it will be integrated in one of the next CMSSW_13_0_X IBs after it passes the integration tests and once validation in the development release cycle CMSSW_14_0_X is complete. This pull request will now be reviewed by the release team before it's merged. @sextonkennedy, @antoniovilela, @rappoccio (and backports should be raised in the release meeting by the corresponding L2)

hold

• Hold integration in 13_0_X as this is intended for CMSSW_13_0_HeavyIon_X .

[cmsbuild]

Pull request has been put on hold by @antoniovilela
They need to issue an unhold command to remove the hold state or L1 can unhold it for all
