Deluge is a BitTorrent client, created using Python and GTK+ (through PyGTK). Deluge is currently usable on POSIX-compliant operating systems. It is intended to bring a native, full-featured client to GTK desktop environments such as GNOME and Xfce. An official Windows port is also available. The program uses the libtorrent C++ library. Up through the 0.4 branch, this was done through the python-libtorrent bindings for Python. In 0.5, the python-libtorrent bindings were merged into the main client as the deluge_core extension. In future releases, it is likely the official Python bindings for libtorrent will be used.

History

Deluge was created by two members of ubuntuforums.org, Zach Tibbitts and Alon Zakai, and was previously being maintained and hosted at Google Code, but has now moved to their own website, deluge-torrent.org.

While under early development, Deluge was known as gTorrent, because it was to be a BitTorrent client for GNOME. When the very first version was released to the public on September 25, 2006, the client was renamed to Deluge to avoid implying that the client was GNOME-only.

The 0.5 release marked a complete rewrite from the 0.4.x code branch. This was to do away with some of the coding conventions in the earlier versions, aiming for a cleaner, more polished result. The second release in the 0.5.x branch, 0.5.1.1, added support for encryption, peer exchange, binary prefix and UPnP.

At about the time of the 0.5.1 release, the two original developers effectively left the project leaving Marcos 'markybob' Pinto and Andrew 'andar' Resch to continue development on their own.

Work has been done to bring Deluge to other operating systems. In version 0.5.4.1, support for both Mac OS X (via MacPorts) and Windows was introduced.

Version 0.5.8.8's release was retracted due to a bug that caused Deluge to crash for some users. Version 0.5.8.9 was released instead, skipping a patched version of 0.5.8.8.

Version 0.6 was renamed 1.0 after the release of the first release candidate.

From version 1.1.1 through version 1.1.3, Windows installers were temporarily unavailable due to the Windows packager leaving the project.

Following 1.1.3, packages for all operating systems were no longer provided by the developers; instead, source tars and community provided packages were released.

Deluge was notable for its resistance to Comcast's bandwidth throttling at the start of its adoption without a change in code, while clients like Vuze (Azureus) and μTorrent had to borrow the method implemented by Deluge.
