![]() ![]() It was also necessary in hybrid swarms to allow dual connections so peers can communicate over v1 and v2 simultaneously.This is sometimes required for situations where there are many v1-only clients in a swarm and v2 hash-info is not fully available, which, when following the specification as-written, prevents pieces from being available over the v2 connection. This was needed to accommodate the new v2 protocol messaging requirements, in particular the piece selection algorithms and file hash field synchronizing with other peers.The new implementation takes full advantage of the fact that when a transfer is only downloading a subset of files, the new v2 protocol allows clients to only download hash data for files that are needed.If managed correctly, this saves bandwidth, time, and memory, especially for extremely large torrents when only a few files are needed. The peer connection logic has been largely re-written with major improvements in several areas. Advanced features such as RSS, IP Filtering, Event SchedulerĪ full BEP-52 implementation has been added to the program.The primary benefit of this is the use of the block-level SHA-2 hash function instead of SHA-1 at the piece level.However, there are also many other changes from the v1 protocol that required a major review and re-write of the torrent/peers/trackers/pieces core logic.Combined version 1+2 torrents are also fully supported.Īll tracker function has been completely replaced with a newly-written implementation.Dual-protocol and dual-interface announcement is now fully supported for each individual tracker.Ī tracker presets feature has been added, which can be accessed from Settings > Transfers > Trackers.These presets can be set by simply right-clicking any transfer in the main window and using the Trackers sub-menu.They are also accessible from the standard tracker-edit dialog, the transfer preload window, and the new seed creation dialog.Ī default preset for newly-loaded transfers can also be selected in the settings window.This will be set into non-private transfers, upon loading, before applying the Individual Tracker Options. ![]()
