Transmission is a BitTorrent client similar to Vuze, or uTorrent. The software is open source, while most of the code is licensed under the GNU General Public License, with select code licensed under the liberal MIT License. The program offers a simple, intuitive interface designed to integrate tightly with any OS.
The OS X-native app is available in both stable and beta form. Both branches have received updates recently. Transmission 1.73 (stable) fixes a bug where user-configured peer limits could be exceeded, uses less memory in some high-peer situations, properly estimates time left to download and sports newer snapshots of libnatpmp and miniupnpc, as far as application changes are concerned. Web client additions include Inspector and Add Torrent buttons for iPhone/iPod Touch and an added location field to inspector.
Transmission 1.74 (beta) sports quite a number of enhancements and improvements on all levels. Developer Eric Petit mentions better data recovery in the case of an OS or Transmission crash; upgrade DHT to version 0.8; if a data file is moved, stop the torrent instead of redownloading it; fix bug that didn't list some peers in the resume file and in PEX; more helpful torrent error messages; DHT now honors the bind-address-ipv4 configuration option; fix Debian build error with miniupnpc; Fix Cygwin build error with strtold and the same update to a newer snapshot of miniupnpc.
The beta release is also 64-bit-compatible. The queuing system will not exclude transfers with tracker warnings, while connections to original torrent files are no longer maintained, these being just a couple of more enhancements carried out by Eric Petit. Bug fixes are also incorporated with Transmission 1.74 (beta): “changing the global per-torrent peer connection limit did not affect the current session;” “changing settings through RPC would result in wrong values being saved for three fields,” the changelog shows.
