USTP is no longer maintained.
The active project is now USTP-Secure, which keeps the UDP/USTP transport idea but makes encryption/authentication mandatory.

- This repository is archived in practice.
- New protocol work should happen in USTP-Secure.
- Existing code here is kept only as historical proof-of-concept material.
