Pure Music 1.88a

For anyone interested, Channel D has just released an upgrade for Pure Music. They have also announced another future upgrade (ver. 1.9), with an expected release of mid-December.

My initial impression is that 1.88a is a sonic improvement over 1.86.
I just did download it myself - Not sure I hear any difference but will know more after my new DAC arrives tomorrow. Thanks for the tip.
Can anybody assist with the steps for the upgrade procedure? I don't find their explanation very clear on the PM user manual.
