In this talk, we revisit the existence theory of weak solutions for the compressible Navier--Stokes system. We propose an approximation scheme that, instead of the classical regularization of the continuity equation (based on the viscosity approximation), employs a more direct truncation and regularization of nonlinear terms and the pressure. This scheme is compatible with the Kolmogorov compactness
criterion for the density.
