After a very long hiatus, we have just released the OpenGrADS Bundle version 2.0.2.oga.1 for Mac OS X and Linux; the Windows version will be released soon. This OpenGrADS version is based on COLA's 2.0.2 release with a couple of additions to the OpenGrADS extensions (a spherical harmonic based Poisson solver and a new satellite orbital masking based on TLE files.) This is meant to be a stable release. Enjoy!
