Release of qBittorrent 5.1
On April 27, 2025, the latest iteration of the torrent client qBittorrent, version 5.1, was officially released. Developed using the Qt toolkit, this open-source alternative to µTorrent has been crafted with a focus on user interface and functionality. The project’s source code, written in C++ and JavaScript, is available on GitHub under the GPLv2+ license. Users can access qBittorrent builds for Linux, Windows, and macOS. The previous major release, qBittorrent 4.0, debuted in November 2017, while version 5.0 was launched in September 2024.
qBittorrent boasts a variety of features designed to enhance the user experience, including:
- Integrated search engine
- RSS feed subscription capabilities
- Support for numerous BEP extensions
- Remote management via a web interface
- Sequential downloading in a specified order
- Advanced settings for torrents, peers, and trackers
- Bandwidth scheduler and IP filter
- Interface for creating torrents
- Support for UPnP and NAT-PMP
The 5.1 release introduces several key enhancements and fixes:
- Resolved previously identified bugs and issues
- Added drag-and-drop support in the torrent content preview widget
- External IP address display in the status bar
- Configurable time interval for saving statistics
- Utilization of reliable pseudorandom number generation functions in Linux and Windows
- New “eXact Length” setting for managing the size of generated magnet links
- Ability to extract a list of trackers from a URL
- Introduction of announce_port setting for specifying the network port for announcements
- Enhanced search interface supporting multiple simultaneous queries, along with search history and open tab memory, plus a button for resending previous searches
- Over 50 modifications to the web interface
- Support for the Thunar file manager
- Localization updates
In late October 2024, the qBittorrent development team released version 5.0.1, which addressed a long-standing bug related to improper SSL/TLS certificate validation that had persisted for 14 years. This fix effectively mitigated a vulnerability that exposed users to potential man-in-the-middle (MitM) attacks.
