March 2026 (2026-03) — Delivered a critical memory-management fix for NACK buffer handling in the pion/interceptor module, enhancing stability and scalability during teardown. The change implements robust cleanup paths across ResponderInterceptor and RTPBuffer, introduces a Clear() method to release retained packets, and ensures proper cleanup on UnbindLocalStream and interceptor Close. Added comprehensive tests to validate release paths. This work directly reduces memory growth during long-running sessions and improves reliability of RTP handling when streams are unbound or closed. Demonstrates strong memory-management discipline, code quality, and cross-team collaboration (Co-authored by ivanlukomskiy and Claude Opus 4.6).
