Nope - no change for me - have you checked that a DCA isn’t assigned to your outputs and turned down? Check your routing/ DCA screen or you could try loading a default factory show and see if that is the same.

Did notice some changes on outputs with graphic EQ’s active in the signal path, notably due to the new types of GEQ filtering available. Changing the type of GEQ in circuit will change both the sound and output level of the channel depending on the source material and how the filters interact with it. Once I found a “sound” I was happiest with by cycling through the various GEQ types, I found that the output levels before/after the firmware update were the same.
I wonder if that might be where the OP’s problem lies.
