- Updated version in Makefile to 0.112.2. - Enhanced SFU server error handling to ignore http.ErrServerClosed. - Added TURNS (TURN over TLS) configuration options in TURN server and related components. - Updated firewall rules to include TURNS ports and modified related tests. - Implemented self-signed certificate generation for TURNS. - Adjusted TURN server to support both UDP and TCP listeners. - Updated WebRTC and SFU components to accommodate new TURNS configurations.
