qBittorrent 4.5.2

qbittorrent

The qBittorrent project aims to provide a Free Software alternative to µtorrent. qBittorrent is an advanced and multi-platform BitTorrent client with a nice user interface as well as a Web UI for remote control and an integrated search engine. qBittorrent aims to meet the needs of most users while using as little CPU and memory as possible. qBittorrent is a truly Open Source project, and as such, anyone can and should contribute to it.

Note: Users of Windows 10+ can also use the Qt6 version of the installer. Qt6 offers better HiDPI compatibility. The Qt6 version isn't tested much. The v4.4.x series will probably be the last one that supports Qt5 and therefore Windows 7 and 8. It will see releases at least until the summer of 2022.
