CyberDuck quacks its way from Macintosh to Windows

David Kocher has announced the final release of CyberDuck 4.0 for Mac and Windows. CyberDuck is a FTP client that is also capable of providing access to various cloud-based storage providers, including Google Docs, Amazon S3, WebDAV and Windows Azure (but not Windows Live SkyDrive) through a desktop application.

Version 4.0 represents the first official release for Windows users -- the version number has jumped straight to 4.0 to provide synchronicity with the Mac client, which was developed first.

Version 4.0 includes several new features that will be new to Mac users: support for Dropbox and Windows Azure, plus enhancements for existing providers, such as the ability to upload up to 5TB in a single file to Amazon S3 servers. Mac users can now also upload files using the Finder context menu. A number of bug fixes have also been introduced -- it's now possible to view all documents stored in Google Docs regardless of the document's owner, for example.

CyberDuck 4.0 is available for both Mac (OS X 10.5 or later) and Windows (XP, Vista and Windows 7), and is open source.
