Yazsoft has updated its powerful download manager for Mac OS X, Speed Download 5. Version 5.2.0 is a free update to existing users and can be acquired right here, on Softpedia. The new version adds optimizations for Mac OS X 10.5.7 and several under-the-hood changes.

Yazsoft claims to have optimized and turbo-charged Speed Download 5 for Mac OS X 10.5.7, while making some changes to prepare SD for the next-generation Mac OS X (Snow Leopard, of course). Miscellaneous changes include several fixes and internal tweaks.

Speed Download 5 is optimized for any Internet connection (dial-up or broadband), and can collect and organize all your downloads. A clean interface with various view modes, a re-engineered “universal” download engine optimized for maximum performance, a powerful database to manage all downloads, uploads, and file transfers, Mac iDisk integration and auto-resuming file transfers are just some of the noteworthy features in Speed Download 5. A new, fully featured, built-in FTP client has been added in the first stable release of Speed Download 5. It uses encrypted file sharing between SD5 users.

A “lite” version of the software is also available – currently at version 1.1.0 (second link). Using Speed Download requires any Internet connection and a Mac OS X-compatible Internet browser. Speed Download is a Universal Binary, compatible with Intel and PowerPC processors. Mac OS X 10.4.11 (the latest available version of Tiger) is still supported.
