Download Engine 3.9.0

Download Engine 3.9.0 expands torrent support from opening a link to managing and optionally sharing completed files. It includes the Windows opening features introduced in 3.8.0.

What changed

• Open .torrent files from Explorer, click magnet links in a connected browser, drag files onto the app, or review copied magnets. First-use consent and file selection stay in place, with duplicate pending requests combined.
• Opt in separately to seeding completed torrents and accepting incoming connections. Both are off by default. Upload limits and quotas apply, and Stop all also stops sharing.
• Scan multi-file torrents with progress, individual results and cancellation. External antivirus apps receive a folder request and still require you to review their results.
• Move or rename completed torrent folders, with recovery for interrupted moves and protection against overwriting existing destinations.
• Keep Pause, Resume and Stop all responsive when scheduler maintenance runs slowly. Includes torrent metadata, tracker and peer resource-limit hardening.
• Updated the README, website, guides and localized release notes for the torrent workflow.

Use torrents at your own risk. Downloaded files may contain malware, and peers can see your IP address. Enabling uploads or seeding shares file data with other peers. Only download and share content you are authorized to use. Antivirus scans cannot guarantee that a file is safe.

Downloads

Choose UnsignedSetup.exe for the Windows x64 installer, or Unsigned-windows-x64.zip for a portable copy. FFmpeg is bundled in both, together with its license and source information. These builds are unsigned; use SHA256SUMS-3.9.0 to verify your downloaded files.

Separate Chrome/Brave, Edge and Firefox extension ZIPs, plus the matching source ZIP, are attached. The source ZIP contains source and license materials, not executable binaries. Firefox store updates are separate from this GitHub release.

Checks and limits

Validated using isolated torrent transfer/control/recovery fixtures, extension tests, native UI checks, and Windows installer install/upgrade/uninstall checks. Release verification checks the source inventory, all asset checksums and bundled FFmpeg files. The website was checked at desktop and mobile widths.

Torrents pause while a proxy is enabled because the app's proxy does not carry torrent traffic. Adding torrents through CLI, scripts or MCP, peer encryption, uTP, web seeds and automatic router port mapping remain unsupported. Public-swarm interoperability and real antivirus-product behavior are not certified by the isolated fixture tests.
