The Transmission Project has announced the release of Transmission 2.20 Final, the stable result of a relatively long beta testing process which culminates with a hefty bag of fixes and tweaks to improve the popular BitTorrent client.

Available immediately to Softpedia readers rocking Mac OS X, as well as to those running Linux and other desktop OSes, Transmission 2.20 is now more efficient as it uses fewer system resources (CPU, RAM).

The developers note native Mac, GTK+ and Qt GUI clients; ideal daemon for servers, embedded systems, and headless use; remote control support via Web and Terminal clients; Local Peer Discovery; and full encryption, DHT, PEX and Magnet Link support, to name some highlights.

Transmission 2.20 also fixes issues in the German and Spanish localizations, adds support for ZIP and other compression formats in the blocklist downloader, and brings a number of unspecified interface tweaks for the Mac OS X  version of the application.

As noted in previous (beta) releases of Transmission 2.20, the changes spanning all platforms include the following:

 * Remember downloaded files when a drive is unplugged  * File re-verification is no longer needed in some situations  * Fix "Too many open files" error  * Show the total downloading and seeding time per torrent  * Fix webseeds  * Better support for IPv6-only trackers  * Add the ability to shutdown Transmission sessions via RPC  * NAT-PMP and UPnP now also map the UDP port  * Update the DHT code to dht-0.18  * Faster parsing of bencoded data  * Improve support for running scripts when a torrent finishes downloading  * Fix reannounce interval when trackers return a 404 error  * Fix checksum error on platforms running uClibc 0.9.27 or older  * Fix memmem() errors on Solaris.

Web client changes include the ability to right-click a torrent when using Firefox, Firegestures, and Ubuntu.

The Transmission team was also able to fix an error when replacing substrings in tracker announce URLs, while webseeds are now displayed in transmission-show, according to the release notes.

Transmission for Mac requires OS X 10.5 (Leopard) or later.
