Downloading Redactor

How do I download Redactor? The Yii extension for Redactor directs me to the Redactor website to download the code, but I am presented with a "Buy Redactor" page. I think Yii purchased an OEM license, so I can download it for free if I am using it for Yii, right? How do I download it for free?

Yii extension for Redactor: On the extension wiki, click "Download Redactor" and see where it takes you.

Thanks for any help.
