Microsoft announced the road forward for IronRuby and IronPython.  These two dynamic language implementations that incubated internally the last few years. We have released several versions of both language environments (IronPython releases and IronRuby releases), and all of the source code has been released under open source licenses (recently moved to Apache License V2.0). For more information, refer Jason’s blogpost “New Components and Contributors” talks about this.
