We use all available baryon acoustic oscillation distance measurements and Hubble parameter data to constrain the cosmological constant, dynamical dark energy, and spatial curvature in simple cosmological models. We find that the consensus spatially flat CDM model provides a reasonable fit to the data, but depending on the Hubble constant prior and cosmological model, it can be a little more than 1 away from the best-fit model, which can favor mild dark energy dynamics or non-flat spatial hypersurfaces.
