Does someone know when nhibernate 1.2.0.Beta3 will be released? I found out that there will be an Informix dialect included which I need for my application.

Or exists another possibility of getting Informix working with nhibernate at the moment?

You can either use the SVN trunk version or only take this dialect (+driver), compile it in a separated library and use its name in your configuration.

Well, the svn trunk works for me, but the Informix dialect is imcomplete on some datatypes. I am trying to complete the dialect. If I finished the dialect what is the best way to give the solution back to this project?

Submit it to JIRA.
