Yazsoft (http://www.yazsoft.com) has released Speed Download 5.3, the latest version of its Mac OS X download manager that combines four products: a download manager with auto-resuming downloads, a secure FTP client, a file sharing utility with full encryption, and .Mac/iDisk/WEBDAV connectivity. Version 5.3 introduces a Safari extension for even better Safari integration.

Speed Download requires Mac OS X 10.6.8 or higher. It costs US$25 for a single-user license. You can also obtain it in the $35 Mega Bundle, which includes all of Yazsoft’s apps. Speed Download is available in US English, French and Polish localizations.
