"Improved the Rec-Arm behavior" 8.5.20

Regarding this entry in the 8.5.20 patch:-
B-16259 MIXCONSOLE: Improved the Rec-Arm behavior when selecting channels linked to VCA Faders
How is it improved? Activating “Record Arm” and/or “Monitor” on a single channel in a VCA group still affects all channels on my system. I assumed that this was what had been “improved”.
