"We are pleased to announce the release of a new Beta (version 0.6) of the Gardens Point Ruby.NET compiler. Implementation is not yet complete but we have now implemented the vast majority of Ruby's builtin classes and modules. We have fixed large numbers of existing bugs, but many still remain. We have not yet implemented continuations or Ruby threads but support most other language features.
In addition to passing all 871 tests in the samples/test.rb installation test suite of Ruby 1.8.2, we are now able to support the standard Ruby test unit library and pass most of the 1864 assertions in the test/ruby test directory."
