Looking in the JIRA, there are two outstanding issues for 2.0.3.CR2 and none for 2.0.3.GA. The date on the nightly for 2.0.3 is Sept 5, 2008.
Is there a planned release date for 2.0.3.GA? I am trying to use Dan Allen's book for a course in January, and it would be nice to have a stable version 2.0.3 for that. The text's code does not work in the 2.1 branches yet.
