Transmission 4.1 Open-Source BitTorrent Client Released as a Massive Update
Coming almost three years after Transmission 4.0, the Transmission 4.1 release introduces support for IPv6 and dual-stack UDP trackers, support for trackers that only support the old BEP-7 module, optional sequential downloading, support for IPv6 Local Peer Discovery, and support for using a proxy server for web connections.
Transmission 4.1 also introduces a new option to verify a torrent immediately after it finishes downloading, the ability to cache IP addresses used in global communications and use them to fix the UDP6 warning log spam, as well as support for sending an IPv4 parameter during the Extension Protocol handshake.

Transmission 4.1 makes my favorite BitTorrent client even better
Transmission is my favorite BitTorrent client, with excellent ports to Windows, Linux, macOS, and headless servers. Now, Transmission 4.1 has arrived after over a year of development, and it has some great changes.
First, this release has several performance improvements. Downloads using the Micro Transport Protocol (μTP) are now faster than with previous versions, and CPU and RAM usage has been reduced across several functions. Sequential downloads is now available as an option when adding torrents, so you can choose individual files in a torrent that should be downloaded first.
Transmission 4.1 has also switched all the icons for menus and toolbars to their native system equivalents—SF Symbols on macOS, Segoe Fluent on Windows 11, Segoe MDL2 on Windows 10, and XDG standard icons on other platforms. That helps Transmission fit more with the rest of your system, and it certainly looks a bit better on my Mac.
