qBittorrent 4.5.0

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.

qBittorrent 4.5.0 release notes:

New icon theme, new color theme and better startup time when using many torrents.
WINDOWS: Only 64-bit builds will offered from now on.
NOTE: The default builds for all OSs switched to libtorrent 1.2.x from 2.0.x. Builds for libtorrent 2.0.x are also offered and are tagged with lt20. The switch happened due to user demand and perceived performance issues. If until now you didn't experience any performance issue then go ahead and use the lt20 builds.
