 +<hidden TTP95-20  Three-loop QCD Corrections to \delta\rho, \DELTA r and \Delta\kappa > QCD corrections to electroweak observables are reviewed. Recent results 
 + on contributions from the top-bottom doublet 
 + of ${\cal O}(\as^2)$ to $\drho$, $\Delta r$ and $\Delta\kappa$ are presented. 
 + It is demonstrated that the first three terms 
 + in the expansion in $M_Z^2/M_t^2$ provide an excellent approximation to 
 + the exact result. 
 + Calculational techniques are briefly discussed.
