v2.5.5 - Runtime BitTorrent Endpoint Control

Breaking Changes

bt-external-ip is now session-wide and can no longer be configured per download or through input-file entries.

Summary

This release adds live BitTorrent listener rebinding and consistent external endpoint announcements without interrupting established peer connections.

Added

• Added runtime listen-port changes through aria2.changeGlobalOption.
• Added bt-external-port for NAT and port-forwarding configurations.
• Added aria2.getBtEndpoint to report active local and advertised endpoints.

Changed

• Tracker, DHT, and BEP 10 announcements now refresh after endpoint changes.
• Local Peer Discovery continues to publish the actual local listener port.
• External IP configuration is validated and managed globally.

Fixed

• Failed listener replacements now preserve the previous working listener.
• Endpoint changes during tracker activity are announced immediately after the active request completes.
