JAGS 1.0.4 is released. I did not plan this, but I had to fix a potential security vulnerability in libltdl, which the command line interface uses to load modules. Thanks to Dirk Eddelbuettel, who maintains the Debian package for JAGS, for letting me know.
Meanwhile, I am trying to put the finishing touches on the glm module for JAGS 2.0, which should improved mixing in generalized linear (mixed) models. When this is done, JAGS 2.0 should be ready for release.
