## Changes
+20220612: The rp2040 micro-controller now has a workaround for the
+"rp2040-e5" USB errata. This should make initial USB connections more
+reliable. However, it may result in a change in behavior for the
+gpio15 pin. It is unlikely the gpio15 behavior change will be
+noticeable.
+
20220407: The temperature_fan `pid_integral_max` config option has
been removed (it was deprecated on 20210612).
