If "Fan:VariableVolume" in the "Supply Air Fan Object Type" field, it needs to be changed to "Fan:SystemModel". A "Fan:SystemModel" object need to be created based on the former "Fan:VariableVolume" object. A fan power curve will be created as well that holds the "Fan Power Coefficient i" in Fan:VariableVolume.
Cooling and Heating: inserted "Heat Recovery Inlet Node Name", "Heat Recovery Outlet Node Name", and "Heat Recovery Reference Flow Rate" fields; new optional "Heat Recovery Capacity Modifier Function of Temperature Curve Name", "Heat Recovery Electric Input to Output Ratio Modifier Function of Temperature Curve Name" fields
Cooling: new optional "Maximum Heat Recovery Outlet Temperature", "Thermosiphon Capacity Fraction Curve Name", and "Thermosiphon Minimum Temperature Difference" fields
Heating: new optional "Minimum Heat Recovery Outlet Temperature" field

Sizing:Zone: new optional "Type of Space Sum to Use" field
AirTerminal:SingleDuct:SeriesPIU:Reheat and AirTerminal:SingleDuct:ParallelPIU:Reheat: new optional "Fan Control Type", "Minimum Fan Turn Down Ratio", "Heating Control Type", "Design Heating Discharge Air Temperature", and "High Limit Heating Discharge Air Temperature" fields
InternalMass: field "Zone or ZoneList Name" is no longer required
I left things alone and just put a comment in FT: "As of E+ v24.2, Zone Name is ignored when Space Name is specified"

@wsjsxn Not sure I follow here. We're in the process of updating to v24.2.0, so your question seem too early perhaps? Anyways, in the end, you'll just be able to add it to a tertiary loop for heat recovery.
Enhancement Request
Once v24.2-IOFreeze is released, we should update to it.
