I can try to make the changelog clearer, but that wasn't my
motivation.  As I mentioned in the email with the patch, iphlpapi is
only needed once per process by rpcrt4, so I manually load it so that
I can also unload it as soon as it's done.  This is in contrast to
ws2_32, where iphlpapi may be needed more than once.
