Partial bases and homological stability of ${\mathrm{GL}}_n(R)$ revisited

Let $R$ be a unital ring satisfying the invariant basis number property, that every stably free $R$-module is free, and that the complex of partial bases of every finite rank free module is Cohen–Macaulay. This class of rings includes every ring of stable rank $1$ (e.g. any local, semi-local or Artinian ring), every Euclidean domain, and every Dedekind domain ${\mathcal{O}}_S$ of arithmetic type where $\mathrm{\mid }S\mathrm{\mid }>1$ and $S$ contains at least one non-complex place. Extending recent work of Galatius–Kupers–Randal-Williams and Kupers–Miller–Patzt, we prove that the sequence of general linear groups ${\mathrm{GL}}_n(R)$ satisfies slope-$1$ homological stability with $\mathbb{Z}[1\mathrm{/}2]$-coefficients.
