"Airspeed not healthy" after updating from 4.1.0 to 4.2.3

I haven’t changed any part of my hardware or settings (that I know of), yet the FC is failing the airspeed pre-arm check. (I am using an airspeed sensor.) Is this related to the FW update? What is a good way to troubleshoot this?

Looks like the same, unresolved issue Airspeed I2C MS4525D0 Not Working!

edit: I started getting (incorrect, but working) readings. The ARSPD_TYPE was set to 2, instead of 1. I didn’t change it though… I wonder if there is an attempt at an automatic conversion of settings during firmware updates.
