Intersect's Parameter Committee proposes to update the Plutus V3 Cost Model via a Parameter Update governance action to enable the new Plutus primitives that will be available following the van Rossem hard fork (to Protocol Version 11), to enable all Plutus primitives in Plutus V1 and V2 as well as Plutus V3, and to change settings for some existing Plutus primitives. Note that the new primitives will not be enabled in Protocol version 10, but only following the enactment of the hard fork to Protocol Version 11. However, the changes for existing primitives will happen immediately on enactment of this governance action.
