@mattmilten @simonbowly was there a change in the printing behavior in Gurobi 9.5? Does it now print out every non-default parameter when you create a model? (Our tests now have 1500 lines of "Set parameter ..." prints.)

[mattmilten]

Please excuse the delay! yes, there has been a change in how the outputflag parameter is handled in different environments - we hope to fix this again in the next release. Please excuse the inconvenience!

@mattmilten I logged a new support ticket because we're still seeing this printing with Gurobi 9.5.1: https://support.gurobi.com/hc/en-us/requests/28435
