 # Changelog
 
+## 2026-03-20 - 25.17.3 - fix(repository)
+no changes detected
+
+
+## 2026-03-20 - 25.17.2 - fix(rustproxy-http)
+enable TLS connections for HTTP/3 upstream requests when backend re-encryption or TLS is configured
+
+- Pass backend TLS client configuration into the HTTP/3 request handler.
+- Detect TLS-required upstream targets using route and target TLS settings before connecting.
+- Build backend request URIs with the correct http or https scheme to match the upstream connection.
+
 ## 2026-03-20 - 25.17.1 - fix(rustproxy-routing)
 allow QUIC UDP TLS connections without SNI to match domain-restricted routes
