v4.5.0 shifting issue... maybe...

So, on my last Zwift ride every once in a while it seemed like when I pressed the button to shift to a harder gear it would shift 2 cogs instead of one.  Out of curiosity I just tried it outside of Zwift and noticed that if I hold the shift button the bike will shift multiple cogs.  Has this always been a thing?  I've never noticed it before and it happened at least twice that I remember on my last ride.  

I do not remember ever having this happen previous to installing this firmware so I'm guessing it's either a new feature or it's been there but the long press delay time has changed.  Anyone else experience this?
