We are pleased to announce the official release of OpenMx version 2.9.6. (update: 2.9.9 is now available - for users, this is near-identical).
CRAN
Users of Windows and Linux/GNU can install OpenMx v2.9.6 from CRAN with the usual `install.packages("OpenMx").
note: CRAN has not been able to build functioning OpenMx binaries for MacOS since OpenMx v2.9.6.
Advanced MacOS users can still obtain version 2.9.9 source via CRAN, but the Mac onto which you are installing the package must be configured to build it from source.
