Popular free and open-source FTP program Cyberduck has been updated to v3.8, bringing a number of new features and fixing more than a dozen issues. The big focus of the update is support for both Amazon's CloudFront content distribution network (CDN) and Swift storage (Openstack) installations. It also improves the speed of SFTP transfers, interoperability with third-party S3 tools and its ability to connect to HTTP/HTTPS proxies.
