v3.9.8-beta.4 — Major Aria2 Next Engine Overhaul

on GitHub

What's Changed

This is a major engine update built around Aria2 Next 2.6.1. The download backend has been extensively restructured around mature protocol libraries and a unified application-managed runtime. Scattered legacy aria2 state and hand-built transfer implementations have been removed: HTTP and HTTPS now use libcurl, while BitTorrent now uses libtorrent—the same proven foundation used by professional clients such as qBittorrent. This delivers substantially better expected BitTorrent performance, stability, protocol compatibility, and maintainability.

✨ New Features

• libtorrent BitTorrent backend — Handles metadata, peer communication, selective downloads, resume data, verified progress, seeding, and runtime limits through a mature production library.
• libcurl HTTP backend — Adds HTTP/2 support, stricter range handling, improved certificate processing, and asynchronous DNS resolution.
• Torrent inspection — Reads torrent metadata before task creation and supports reusable file selection.
• Sharing controls — Adds explicit BitTorrent and ED2K sharing lifecycle controls.
• Engine-ready notification — Restores localized startup confirmation when Aria2 Next is ready.

🛠 Improvements

• Centralized engine configuration, session data, torrent recovery state, and runtime files under the Motrix Next-managed engine directory.
• Removed scattered legacy aria2 files and obsolete TLS, networking, crypto, and transfer backends.
• Improved selective-download handling for torrent files and magnet links.
• Refined task creation, recovery, update checking, and download settings layouts.
• Added validation for user-editable numeric engine options.
• Improved ED2K state persistence, completed-range handling, option normalization, resolver behavior, and speed accounting.
• Replaced the custom Windows TLS implementation with the unified libcurl transport.

🐛 Bug Fixes

• Fixed inaccurate transfer speed calculations in Aria2 Next.
• Fixed inconsistent BitTorrent file-selection and resume behavior.
• Fixed stale or incomplete task state during sharing and recovery transitions.
