  1. ↑ 1.0 1.1 1.2 1.3 1.4 Via bundled python-osc dependency; bundle support requires using python-osc's API directly.
  2. ↑ Receive fully supported including nested bundles; send requires low-level OscWriter API.
  3. ↑ t (timetag) is receive-only.
  4. ↑ h, d, t with lossy type mapping to Python float.
  5. ↑ Minimal VRChat-specific subset; only serves / and /?HOST_INFO.
  6. ↑ Returns OSC_PORT only; missing NAME, EXTENSIONS, OSC_IP, OSC_TRANSPORT.
  7. ↑ 7.0 7.1 Hardcoded to /avatar and /tracking paths; not a dynamic OSC address tree.
  8. ↑ 8.0 8.1 Advertised as supported in HOST_INFO extensions but not implemented at the node level.
  9. ↑ 9.0 9.1 Supported on the node level but not advertised in HOST_INFO extensions.
