Mplus Version 6.12 is available for Windows, Mac OS X, and Linux for both 32- and 64-bit computers. In Version 6.12, the Mac OS X version is available using a new editor in addition
to the command line. Mplus Version 6.12 contains corrections to minor problems that have been found since the release of Version 6.11. Two minor additions have also been made to
accommodate the analyses in the Muthen (2011) paper Applications of causally defined direct and indirect effects in mediation analysis using SEM in Mplus.
A normal distribution function (PHI) has been added to the DEFINE and MODEL CONSTRAINT commands and the FREQWEIGHT option is now available with ESTIMATOR=BAYES.
