  We present the results of a new analysis of the data of the MiniBooNE
experiment taking into account the additional background of photons from
$\Delta^{+/0}$ decay proposed in arXiv:1909.08571 and additional contributions
due to coherent photon emission, incoherent production of higher mass
resonances, and incoherent non-resonant nucleon production. We show that the
new background can explain part of the MiniBooNE low-energy excess and the
statistical significance of the MiniBooNE indication in favor of short-baseline
neutrino oscillation decreases from $5.1\sigma$ to $3.6\sigma$. We also
consider the implications for short-baseline neutrino oscillations in the 3+1
active-sterile neutrino mixing framework. We show that the new analysis of the
MiniBooNE data indicates smaller active-sterile neutrino mixing and may lead us
towards a solution of the appearance-disappearance tension in the global fit of
short-baseline neutrino oscillation data.
