Updating Mu-so firmware

I have recently bought a Mu-so and I see from the Naim app that Firmware Update 1.5.0 is there to be applied.  However, under the Show Old Versions tab, I am also given the option to apply Updates 1.2.0 and 1.3.0.  Should I apply these 2 versions before 1.5.0?  (Under Settings-About, my “Streamer version” is shown as 1.2.00).  I should be most grateful for your advice.  Roger
