A new Pull Request was created by @Martin-Grunewald (Martin Grunewald) for CMSSW_9_4_X.

It involves the following packages:

Configuration/HLT
HLTrigger/Configuration

@Martin-Grunewald, @silviodonato, @cmsbuild, @fwyzard can you please review it and eventually sign? Thanks.
@makortel, @geoff-smith this is something you requested to watch as well.
@davidlange6, @slava77, @fabiocos you are the release manager for this.

This pull request is fully signed and it will be integrated in one of the next CMSSW_9_4_X IBs (tests are also fine) and once validation in the development release cycle CMSSW_10_2_X is complete. This pull request will now be reviewed by the release team before it's merged. @davidlange6, @slava77, @smuzaffar, @fabiocos (and backports should be raised in the release meeting by the corresponding L2)

@Martin-Grunewald @franzoni @klute do I understand correctly that this change is effectively modifying the HLT in simulation compared to the existing production? Would not this mean breaking backward compatibility of physics content?

[Martin-Grunewald]

@fabiocos
The new HLT:PRef menu is the menu used in 2017 for the 5 TeV pp reference run. It is separate from any other standard data taking (pp, HI, ...); as far as I know the old one has not been used in any MC production for a long time (it dates back to 2015), so there is no breakage. In fact the update in this PR is requested for a planned MC production with the 2017 5 TeV pp ref menu which this PR updates to.

Confirming that no official MC was run with the previous version of the HLT:PRef menu in 94X and that we are eagerly awaiting a new CMSSW_9_4_X release with this PR included so that official MC can begin for the 2017G pp run at 5 TeV.
