Gromov's minimal volume conjecture for finite-volume hyperbolic manifolds

Let $(M^n,g_0)$ be a complete hyperbolic manifold with finite volume, where $g_0$ is a hyperbolic metric on $M^n$. The minimal volume of $M$ is denoted by

$${\rm Min\,Vol}(M)=\inf\{\operatorname{Vol}(M,g): g\text{ is a Riemannian metric on }M\text{ with }|K_g|\leqslant 1\}.$$

Gromov's conjecture. For every complete hyperbolic manifold of finite volume,

$${\rm Min\,Vol}(M)=\operatorname{Vol}(M,g_0).$$

This conjecture proposes that the hyperbolic metric realizes the minimal volume among metrics with sectional curvature bounded in absolute value by $1$. The supplied source does not state whether the conjecture has been resolved.
