processone/stun

This system is a STUN/TURN protocol library for Erlang/OTP that provides full TURN support alongside STUN functionality. It manages network connections through a dedicated listener and acceptor architecture, handling protocol definitions and data exchange according to RFC standards. The implementation relies on modern Erlang patterns and integrates with the OTP logging system for operational visibility.

The library has been upgraded to version 1.2.23 and now includes full TURN (RFC 5766) support alongside STUN. The internal architecture has been refactored to use a new \stun\_listener\ and \stun\_acceptor\ system for managing connections, replacing the previous direct supervisor model. The application now depends on \fast\_tls\ and \p1\_utils\, and the license has been changed to Apache 2.0. Logging has been updated to use the modern OTP logger with metadata filtering where available, and the codebase has been modernized to use maps instead of proplists/dicts and \p1\_fsm\ instead of \gen\_fsm\.

The STUN/TURN include files have been updated to align with RFC 6156 (TURN Extension for IPv6) and modern Erlang/OTP standards. The \stun.hrl\ file now defines additional STUN methods (such as Allocate, Refresh, Send, Data, Create Permission, and Channel Bind) and attributes (including Channel Number, Lifetime, XOR Peer/Relayed Address, Requested Address Family, Even Port, Requested Transport, Dont Fragment, and Reservation Token) required for full TURN support. The STUN magic number and bit-manipulation macros have been updated to use hexadecimal literals for clarity and correctness. A new \stun\_logger.hrl\ file has been added to wrap the OTP Logger, allowing STUN/TURN components to use the standard logging API while maintaining backward compatibility with older logger implementations via the \USE\_OLD\_LOGGER\ flag.

The project now depends on Fast TLS version 1.1.26 and p1\_utils version 1.0.29, replacing the previous versions. This update ensures compatibility with the latest features and fixes in these underlying libraries.
