I guess you are talking about NEWS, not ChangeLog.  It's tru we don't
describe bug-fixes in NEWS, but we do describe incompatible changes.
So I think it would be good to document this change there.  Could you
suggest some simple description of that?  (I don't understand the
details of the use case well enough to do that myself -- how is the
value of url-request-data related to the change we made in
url-http-create-request?)

Thanks.
