Mute other riders ‘ride on’ sound

Since yesterday’s update (1.19.0), the in-game sounds have changed significantly - at least on my iPad (main Zwift device).

No more strident pinging from ride-ons; instead nicely muted blips.
Has this been mentioned in the release notes? I couldn’t find any.

Could it be that Zwift listened, reacted and hasn’t drawn attention to this for some reason?

A (quiet) thumbs up from me, in any case.
