We have examined the impact of new Daya Bay, Double Chooz, and RENOmeasurements on global fits of reactor antineutrino flux data to a variety ofhypotheses regarding the origin of the reactor antineutrino anomaly. Incomparing RENO and Daya Bay measurements of inverse beta decay (IBD) yieldversus $^{239}$Pu fission fraction, we find differing levels of precision inmeasurements of time-integrated yield and yield slope, but similar centralvalues, leading to modestly enhanced isotopic IBD yield measurements in a jointfit of the two datasets. In the absence of sterile neutrino oscillations,global fits to all measurements now provide 3{\sigma} preference for incorrectmodeling of specific fission isotopes over common mis-modeling of allbeta-converted isotopes. If sterile neutrino oscillations are considered,global IBD yield fits provide no substantial preference betweenoscillation-including and oscillation-excluding hypotheses: hybrid modelscontaining both sterile neutrino oscillations and incorrect $^{235}$U or$^{239}$Pu flux predictions are favored at only 1-2{\sigma} with respect tomodels where $^{235}$U, $^{238}$U, and $^{239}$Pu are assumed to be incorrectlypredicted.
