v3.9.1 — Major Core Modernization Release

on GitHub

What's Changed

Motrix Next 3.9.1 promotes the 3.9.1 beta line to stable. This release focuses on the download engine foundation: Aria2 Next completed its core modernization work, moving major protocol and runtime responsibilities to maintained libraries such as libcurl, Boost.Asio, Boost.Beast, Boost.JSON, OpenSSL, and libtorrent-rasterbar while removing obsolete legacy backends and fallback paths. The app side adds better browser-extension download context handling, clearer BitTorrent settings, safer default paths and ports, improved task details, and expanded localization.

✨ New Features

• Modernized Aria2 Next engine — Updated the bundled engine with the completed core modernization work and refreshed sidecar binaries across macOS, Windows, and Linux.
• Browser download context forwarding — Preserves final URL, User-Agent, Referer, Cookie, request headers, and trace metadata for extension-created downloads.
• BitTorrent discovery controls — Added settings for DHT, Peer Exchange, Local Peer Discovery, forced encryption, and per-task peer connection limits.
• Improved BitTorrent seeding controls — Added clearer seeding mode controls with condition-based stop and manual-stop behavior.
• Hindi localization — Added Hindi support across the app and website with automatic locale detection.
• Download history retention — Added completed-record retention controls.
• Port conflict recovery — Added cleaner default port ranges and recovery handling for engine-related ports.

🛠 Improvements

• Ordinary URL downloads now benefit from the modernized libcurl-backed engine path for HTTP, HTTPS, FTP, FTPS, SFTP, and SCP.
• JSON-RPC HTTP and WebSocket handling now use the modern Boost.Beast engine path.
• JSON parsing and serialization now use the Boost.JSON engine path.
• TLS and crypto ownership are centralized around OpenSSL in the engine.
• BitTorrent remains fully backed by libtorrent-rasterbar with cleaner metadata and task handling.
• ED2K progress reporting now exposes clearer verified and in-flight progress fields.
• Improved default download directory resolution on macOS, Windows, and Linux.
• Improved proxy mode behavior and labels.
• Refined BT task detail pages with clearer status, tracker, peer, and health information.
• Improved task metadata fetching display and localization.
• Refined BitTorrent settings layout to match the rest of the preferences UI.
• Updated default engine ports to the 29100-range family.

🐛 Bug Fixes

• Fixed stale browser extension metadata leaking into manual Add Task flows.
• Fixed protected browser downloads losing important request context.
• Fixed system download directory fallback cases where valid user download folders could be ignored.
• Fixed repeated Extension API port auto-switching during engine restarts.
• Fixed engine restart reconciliation so Motrix Next does not treat its own Extension API listener as an external conflict.
• Fixed unverified BitTorrent files being allowed to seed.
• Fixed several ED2K search timeout and cancellation messages.
• Fixed Linux and Wayland hardware-rendering stability hints.
• Fixed task and speed display wording inconsistencies.
