libts3ds v0.1.0

Changelog

libts3ds 0.1.0 - 2026-07-12

First hardware-validated release of the native Nintendo 3DS transport.

Added

• Direct UDP with STUN, encrypted DISCO validation, and CallMeMaybe.
• Tailscale Peer Relay discovery, allocation, Geneve transport, and path
  confirmation.
• Deterministic auto, direct, peer-relay, and derp path policies.
• Private lwIP outbound TCP suitable for libssh2 callbacks.
• Incremental streaming MapResponse receive and peer-region DERP routing.
• Background control reconnect after suspend or remote EOF.
• Atomic state persistence with backup recovery.
• Caller-selectable logging and detailed last-error diagnostics.

Changed

• Peer Relay-capable policies use a 1024-byte TUN MTU to avoid relay-path MTU
  black holes found on physical hardware. Other policies use 1280.
• DERP maintains separate home and peer-region connections and reconnects with
  bounded backoff.
• Auth keys are cleared from library-owned memory after registration but are
  never removed from caller configuration.

Verified

• Registration and identity reuse on physical Nintendo 3DS hardware.
• Interactive SSH over direct UDP, Peer Relay, and DERP.
• Suspend/resume recovery and long-running shell traffic.
• Host unit tests and full devkitARM builds with warnings treated as errors.
