Onyx, a free GUI for OpenMX with built-in LaTeX support, looks pretty cool. 

OpenMx 1.0

Just realized that this SEM package for R has released version 1.0. Great...

OpenMx with mixture distribution support

A new version of OpenMx is out; this time it comes with mixture distribution, according to this announcement. I can't wait to test the new features out!

Right now it cannot be build from source because there are some comparabilities between OpenMx and R 2.10.0, but I assume this will be resolved soon.

And the development seems to be quite active.
