Version 4.0 of BitTorrent client Transmission released

Version 4.0 of the well-known open source, free, and cross-platform BitTorrent client Transmission has been released. This upgrade brings a host of new features and performance enhancements. The Transmission

4.0 release, which has been in development for more than a year and arrives more than 2.5 years after Transmission 3.0, brings support for BitTorrent v2 and hybrid torrents, support for IPv6 blocklists, and a completely redesigned Web client with full mobile support, including support for dark mode and full-screen.

The ability to set ‘default’ trackers that can be used to announce all public torrents, and the option to omit potentially identifying information like user-agent and date created when creating new torrents are all new features.

Transmission 4.0 adds customisable anti-brute force settings, the capability to retrieve magnet metadata, support for changing the GTK client’s progress bar colour based on the torrent state, an updated ‘Details’ dialogue that now displays the date a torrent was added, and faster rendering of lengthy file lists.

A new feature called torrentadded-verify-mode allows users to force-verify newly added torrents. Additionally, the TransmissionQt and Transmission-Web remote control GUIs now employ the

RPC API’s ‘table’ mode, which results in smaller payloads and less bandwidth consumption.

The entire code base has also been converted from C to C++, the GTK client has been upgraded to GTK 4 and GTKMM, and the Web client has been completely rewritten in contemporary JavaScript.
