There has been much progress in measurements of charmless hadronic B decays during 1997. Building on the previous indications from CLEO and LEP, CLEO now has clear signals in five exclusive final states: K+π^, K0π+, etapr K+, etapr K0, and omega K+. The branching fractions for the etapr K modes are several times larger than the others. A similar strikingly large signal has been seen in the inclusive decay, B->etapr XS. All of these signals would appear to be dominated by hadronic penguin processes.
