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