AnInsomniacy.Aria2Next 2.4.6

Maintained aria2 fork with extensive bug fixes and modernized architecture

aria2 is remarkable open source software. For over a decade it has been one of the most capable download engines available, trusted by countless tools and users worldwide. We are deeply grateful to the original authors and contributors of the aria2 project. They built something that has stood the test of time, and that enduring quality is the best testament to their vision and craftsmanship. But upstream development has slowed dramatically in recent years. Dependencies grew stale, builds broke on modern platforms, and a backlog of bugs went unaddressed. We picked up the baton: migrated the codebase to a modern build framework, triaged and fixed a substantial number of upstream issues, and introduced ED2K protocol support for the first time. A full audit trail is preserved in docs/maintenance/upstream-issue-review/matrix.csv. Aria2 Next is an actively maintained aria2-compatible engine for everyone, and it is also the embedded engine used by Motrix Next. Original interfaces, including options, configuration, sessions, JSON-RPC, and libaria2, remain intact so downstream projects get a seamless upgrade. The focus is straightforward: release reliability, current dependency baselines, and ongoing compatibility fixes. Same engine, renewed foundation.
