This may be old news, but somehow I missed it until yesterday. Rails 2.0 released last month. The closet Rails dev I pretend to be in my spare time is jumping for joy. NetBeans 6.0 also released last month. Normally, this is just news to the Java crowd, but this release integrates support for Ruby and Rails development. The support includes code completion, integrated debugger, integrated source control, and more. It has me seriously considering switching from TextMate for Rails development.
