The developers of qBittorrent, a popular cross-platform Bittorrent client, have released qBittorrent 4.4.0 to the public.
The new version introduces support for a Qt6 version for Windows 10 and later, which promises better HiDPI compatibility according to the developers. The qBittorrent 4.4.x release branch could be the last to support Qt5, and that would also mean it would be the last branch to support Microsoft’s Windows 7 and 8 operating systems. The releases will continue at least until the summer of 2022.
Windows 10 and 11 users can choose to install Qt5 version by then or upgrade to Qt6 version at any time.
An AppImage is provided for qBittorrent under Linux. It “uses the latest versions of Qt6, libtorrent, boost, openssl” and is built on Ubuntu 20.04. The developers note that it is not well tested at this point.
Mac OS X versions are not yet available, but a release is slated for the next few days.
The new version of the torrent client includes several new features and improvements. In addition to the additional support for Qt6, qBittorrent 4.4.0 introduces support for torrents v2 and libtorrent 2.0.x.
The Bittorrent v2 protocol improves the standard by introducing new features. Among the changes, torrents use SHA-256 hashes instead of SHA-1. The new torrent version is not backward compatible, which means that two different versions of an offer are created when version 1 and version 2 torrent files are downloaded or created. The possibility of creating hybrid torrents is however provided.
Another option introduced is the ability to download files from multiple torrents reliably through single file hashes.
The introduction of v2 torrent support ensures that qBittorrent users will not experience any issues while downloading these new torrent versions.
QBittorrent 4.4.0 includes a new option to set the temporary folder by torrent or category, and an option to ignore hash checks for watched folders. Another folder-specific improvement is support for folder-based user interface themes.
Existing installations can be upgraded to the new version as usual. Interested users will find the full changelog, listing all new features, improvements, and bug fixes here.
Support for Windows 7 and 8 will expire later this year when qBittorrent 4.4.x reaches end of life. Users of these systems can use older versions, but they will no longer receive feature updates, bug fixes, or security fixes once development has moved to a new version.
Now you: do you use torrent clients? If so, which one and why this one?
