+## 1.6.6 (25 Jan 2025)
+
+### Fixes
+
+* Consider closures during HTTP/1 header reading as a socket error to silence them by default via `log_client_closures` config flag
+* Send `connection: close` when closing connection on error per RFC9112§9.6
+
+### Enhancements
+
+* Add experimental opt-in trace logging to help diagnose hard to reproduce errors
+* Move CI to 1.18 & improve tests (#459, #461, thanks @grzuy!)
