Updated PM8000 Modbus register list?

[RobGraham]

Is there an updated Modbus register list for the PM8000 firmware v1.4.1?  I have a custom framework built on v1.1.0 with Modbus Slave modules using the 4x116-150 range.  When I try to load the framework on an updated meter, one of the modules is left offline because of a register conflict that doesn't show up on PM8000_Modbus_Map.xlsx. 

Has this document been updated?  Alternately, is there a block of registers that is "future-proof" and will not be used by the firmware?

Thanks!
