I am pleased to announce the release of NHibernate ProxyGenerators 1.0.0 Beta. This release uses NHibernate 2.0.1 GA, allows you to specify a dialect to use when generating proxies (thank you Jaroslav Martásek), and includes example usage with ActiveRecord.
Please visit NHForge.org for downloads, reference information, and tutorials. Any feedback or issues can be sent to the NHibernate Users group and is greatly anticipated.
