Campana's abelianity conjecture for special compact Kahler manifolds

Theorem 1.1: every special compact Kahler manifold has virtually abelian fundamental group, in every dimension. Corollaries: compact Kahler manifolds with κ=0\kappa=0 have virtually abelian π1\pi_1; Campana's Conjecture S and the bimeromorphic Iitaka uniformization (finite etale covers bimeromorphic to tori when γd=n\gamma d=n or the universal cover is Cn\mathbb C^n); holomorphic convexity of universal covers of special manifolds. It does not prove the orbifold or quasi-projective versions in general: the companions give a two-step nilpotent bound for linear images in the open case (credited first to Cao-Deng-Hacon-Paun) and one conditional fourfold orbifold case.
