In the mean time, we have given a couple of workshops on Ωnyx and received many helpful comments on how to improve our program. With this release, we have included several bugfixes for problems reported by our great community of fans. Fixed issues include rendering problems of the graph, corrections to exported model scripts, and many other things.
For no good reason, I attach to this post a picture of a change score model that we have created in Ωnyx.
