AjaxFTP is a drop-in FTP widget that you can use
in Web 2.0 applications. It's modular, skinnable,
and uses the Ruby on Rails Prototype JavaScript
library for a seamless FTP browsing experience.

Download support was added. The method for parsing
FTP results from the server was improved, fixing
one specific reported bug and hopefully averting
many other potential ones later.
