We’re getting closer to V1.0!
Version 0.9.2 fixes 44 bugs (some of the irritating ones like the Rails' bug with :default_url_options and the bug that prevented the RSS standard library from running).
The biggest announcement in the 0.9.2 version, in my opinion, is that IronRuby now has an MSI-based installer for Windows! no need to extract a zip file and do everything yourself anymore.
