Black 24.1 no longer removes blanks within blocks

[xtfocus]

I tried two black versions: black 24.1.1 and 23.3.0. Only the 23.3.0 version removes the REDUNDANT SPACE in the code below

   if not best_rate:
        # REDUNDANT SPACE
        print(f"No match found for {phone_number}")
    else:
        print(best_rate)

I cannot find where this change is documented in the change log here
I would love to know if this change is intended and why. Thanks

The relevant change is "Allow empty first lines at the beginning of most blocks (#3967, #4061)". We started removing these blank lines in Black 23 and lots of people complained, so we decided to stop.
