ZFITTER is a Fortran program for the calculation of fermion pair production and radiative corrections at high energy e(+)e(-) colliders; it is also suitable for other applications where electroweak radiative corrections appear. ZFITTER is based on a semi-analytical approach to the calculation of radiative corrections in the Standard Model. We present a summary of new features of the ZFITTER program version 6.42 compared to version 6.21. The most important additions are: (i) some higher-order QED corrections to fermion pair production, (ii) electroweak one-loop corrections to atomic parity violation, (iii) electroweak one-loop corrections to P,v, production, (iv) electroweak two-loop corrections to the W boson mass and the effective weak mixing angle.
