Dear colleagues, ALPS version 1.2.2 has been released, containing two bug fixes: - a fix for the classical Monte Carlo codes when spin sizes S are given - a fix to the sign problem checker to correctly support site disorder Please download and install the new version if you want to perform classical Monte Carlo simulations and specify spin sizes, or if you want to use non-uniform magnetic fields or chemical potentials in QMC codes, such as for trapped bosons. Best regards Matthias Troyer
