The Ruby In Steel Developer Edition is our commercial product which we aim to ship in January 2007. This will provide unparalleled Ruby IntelliSense features including class, scope and context-sensitive code completion, snippets, tooltip ’hovering’ class and method documentation plus an extremely fast debugger. The Developer Edition has just entered the first phase of restricted-access beta testing.
Meanwhile, we are continuing to enhance the Personal Edition (which includes a wealth of Ruby and Rails features: editing, debugging, project management, project importing and much more besides) which is now and will always be free. Go To Download Page for the Personal Edition.
