The qBittorrent project aims to provide a Free Software alternative to µtorrent. Additionally, qBittorrent runs and provides the same features on all major platforms (Linux, Mac OS X, Windows, OS/2, FreeBSD). qBittorrent is based on Qt4 toolkit and libtorrent-rasterbar.
What's new in this version:
Version 3.1.11 allows relative torrent paths when qBittorrent is already running (pmzqla).
