v2.2.0 - Core Modernization Cutover

on GitHub

Summary

aria2-next 2.2.0 completes the core modernization track. Ordinary URL transfers now use libcurl, JSON-RPC transport uses Boost.Beast, JSON handling uses Boost.JSON, TLS and crypto are OpenSSL-centered, BitTorrent is libtorrent-only, and ED2K remains native with modern progress reporting. This release keeps the aria2-next executable and JSON-RPC workflow, but deliberately prunes obsolete backends and compatibility surfaces.

Added

• libcurl-backed HTTP, HTTPS, FTP, FTPS, SFTP, and SCP transfer ownership.
• Boost.Asio runtime foundation for modern library integration.
• Boost.Beast JSON-RPC HTTP and WebSocket transport.
• Boost.JSON request parsing and response serialization.
• ED2K in-flight progress reporting through RPC for UI progress while verified bytes remain unchanged until validation.
• libtorrent pause-after-metadata support for magnet file selection workflows.

Changed

• Release packaging now builds the modern dependency closure around zlib, OpenSSL, libssh2-for-curl, curl 8.20.0, Boost, and libtorrent-rasterbar.
• Release workflow validation now uses deterministic local transfer smoke tests instead of a fragile third-party public URL.
• Windows x86_64 release builds now use the POSIX MinGW runtime needed by the C++17 and Boost.Asio path.
• Windows runtime dependency checks now allow the system MSWSOCK.dll socket extension dependency.
• Windows ARM64 release builds now pass absolute llvm-mingw tool paths through CMake.
• Storage progress now separates verified completedLength from unverified inFlightCompletedLength.
• Torrent file and magnet ingress now hand raw torrent data and metadata intent to libtorrent instead of keeping native BitTorrent fallback paths.
• CMake dependency detection now expects the modern library set and reports the enabled feature surface at configure time.

Fixed

• Restored libtorrent magnet pause-metadata=true semantics so metadata can resolve before selected payload downloading starts.
• Preserved metadata-pause state across saved libtorrent progress data.
• Fixed RPC progress gathering for file entries without a native bitfield.
• Fixed ED2K build coverage around Kad command headers and Windows macro collisions.
• Updated Android NDK release dependency metadata.

Breaking Changes

• Native BitTorrent engine support is removed; BitTorrent is libtorrent-rasterbar only.
• XML-RPC, Metalink, Metalink3, Metalink4, Expat, and libxml2 support are removed.
• Legacy TLS and crypto backends are removed, including GnuTLS, WinTLS, nettle, libgcrypt, GMP, and internal fallback paths.
• Native HTTP, FTP, SFTP, proxy, cookie, browser-cookie, auth, netrc, wslay WebSocket, and custom JSON parser ownership has been removed or replaced by the modern library owners.
• The optional public C++ libaria2 API, examples, pkg-config file, install rules, and related docs are removed. JSON-RPC is the maintained control surface.
• Removed stale options include follow-torrent, http-auth-challenge, ftp-reuse-connection, ssh-host-key-md, rpc-user, rpc-passwd, rpc-secure, rpc-certificate, and rpc-private-key.
