  We revisit the state of the light element abundances from big bang
nucleosynthesis in early 2024 with particular focus on the derived baryon
abundance. We find that the largest differences between the final baryon
abundances are typically driven by the assumed Deuterium burning rates,
characterized in this work by the underlying code. The rates from theoretical
ab-initio calculations favor smaller baryon abundances, while
experimentally-determined rates prefer higher abundances. Through robust
marginalization over a wide range of nuclear rates, the recently released
$\mathtt{PRyMordial}$ code allows for a conservative estimate of the baryon
abundance at $\Omega_b h^2 = 0.02218 \pm 0.00055$ (using PDG-recommended light
element abundances) in $\Lambda$CDM and $\Omega_b h^2 = 0.02196 \pm 0.00063$
when additional ultra-relativistic relics are considered ($\Lambda$CDM +
$N_\mathrm{eff}$). These additional relics themselves are constrained to
$\Delta N_\mathrm{eff} = -0.10 \pm 0.21$ by light element abundances alone.
