# Changelog
## 2026-02-16 - 25.7.3 - fix(metrics)
centralize connection-closed reporting via ConnectionGuard and remove duplicate explicit metrics.connection_closed calls
- Removed numerous explicit metrics.connection_closed calls from rust/crates/rustproxy-http/src/proxy_service.rs so connection teardown and byte counting are handled by the connection guard / counting body instead of ad-hoc calls.
- Simplified ConnectionGuard in rust/crates/rustproxy-passthrough/src/tcp_listener.rs: removed the disarm flag and disarm() method so Drop always reports connection_closed.
- Stopped disarming the TCP-level guard when handing connections off to HTTP proxy paths (HTTP/WebSocket/streaming flows) to avoid missing or double-reporting metrics.
- Fixes incorrect/duplicate connection-closed metric emission and ensures consistent byte/connection accounting during streaming and WebSocket upgrades.
## 2026-02-16 - 25.7.2 - fix(rustproxy-http)
preserve original Host header when proxying and add X-Forwarded-* headers; add TLS WebSocket echo backend helper and integration test for terminate-and-reencrypt websocket
