Originally developed by Eric Petit, Transmission is a BitTorrent client similar to the popular Vuze. The peer-to-peer (P2P) file-sharing application has select code licensed under the liberal MIT License, but is generally licensed under the GNU General Public License. The program boasts a simple, intuitive interface designed to integrate tightly with any OS. Transmission is a Universal Binary, suitable for both Intel and PowerPC Macs.

Transmission runs natively on Mac OS X, seamlessly configuring your network, banning peers who send corrupted data intelligently, using protocol encryption and built-in Peer Exchange. It also allows you to efficiently ration commodity, only slowing down your system when you actually focus on it.

With the release of Transmission 1.80 final, support has been added for magnet links, and trackerless torrents. The ability to find more peers by announcing to each tier in a torrent's tracker list (rather than only one) is now available as well. Those maintaining the software have improved IPv6 support, PEX sharing with other peers, and enabled a faster management of large peer lists. Transmission should also use less CPU when making encrypted handshakes to peers, and filter bad IP addresses a tad better, these being just a few of the general changes (all platforms) listed in the release notes.

As usual, Mac-specific changes are listed separately, with the changelog saying that a redesigned trackers inspector tab has been set in place with favicons and copy-paste functionality (paste lists of multiple trackers). Other changes include:

· Message log stores all messages and does real filtering;
· Quick Look restored on Snow Leopard;
· Moving data and incomplete folder are now handled by libtransmission;
· Improved reveal in Finder functionality on Snow Leopard;
· Various smaller behavior and interface tweaks;
· German and Simplified Chinese localizations;
· Removed Turkish localization because of lack of localizer.
