Transmission, the popular free open-source BitTorrent client, announced the Beta release of next 4.1.0 version today!

The new release features optional sequential downloading support. Which, is useful when you want to watch large videos/movies while they are being downloaded.

However, I don’t find a graphical option to do the job, but only command line option -seq or --sequential-download for transmission-cli.

It also added IPv6 and dual-stack for UDP trackers. And, settings.json config file now has preferred-transport option, allowing users to manually choose between TCP and UDP when initializing outgoing connections.

While, there’s also sleep-per-seconds-during-verify controls the duration in milliseconds for which the verification process will pause to reduce disk I/O pressure. And, set cache-size-mb: 0 in “settings.json” now disables the disk write cache.

For macOS, the release added “Show Toolbar” toggle option in context menu. It now supports redirects to magnet, Dark Mode and update default font in QuickLook plugin, as well there’s an option to set Transmission as the default app for torrent files.

The Qt UI added a ETA column or info for compact view, and GTK UI now uses system native file chooser dialog. For Web UI, it added support drag-and-dropping torrent file, high contrast theme, and percent digits into the progress bar.

Transmission GTK uses native file chooser

Other changes include:

• Improved µTP download performance.
• Added ability to cache IP addresses used in global communications, fixed UDP6 can’t connect warnings
• Added support for sending an ipv4 parameter during the Extension Protocol handshake.
• Improved libtransmission code to use less CPU and RAM.
• Slightly reduced latency when sending protocol messages to peers.
• And, various bug-fixes.
