We update our previous global analysis of weak neutral current and {ital Z} and {ital W} data in which the parameters {ital h}{sub {ital V}} and {ital h}{sub {ital A}} associated with new heavy physics were constrained, by incorporating recent results on {ital Z} properties and {ital M}{sub {ital W}}. We obtain {minus}0.93{lt}{ital h}{sub {ital V}}{lt}0.33, {minus}1.9{lt}{ital h}{sub {ital A}{ital Z}}{lt}0.27, and {minus}2.5{lt}{ital h}{sub {ital A}{ital W}}{lt}1.5 at 90% C.L., considerably better than the previous limits.
