+## 2026-03-16 - 25.11.15 - fix(rustproxy-http)
+implement vectored write support for backend streams
+
+- Add poll_write_vectored forwarding for both plain and TLS backend stream variants
+- Expose is_write_vectored so the proxy can correctly report vectored write capability
+
 ## 2026-03-16 - 25.11.14 - fix(rustproxy-http)
