RABL (Ruby API Builder Language) version 0.6.12 has just been released. RABL is a popular way to craft service or API responses of all types (JSON, XML, Plist, Msgpack, et al). There have been many improvements in the last few releases including performance, caching, direct renderers, Rails 3.2 support and more.
