 # Changelog
 
+## 2026-03-16 - 25.11.7 - fix(rustproxy)
+prevent TLS route reload certificate mismatches and tighten passthrough connection handling
+
+- Load updated TLS configs before swapping the route manager so newly visible routes always have their certificates available.
+- Add timeouts when peeking initial decrypted data after TLS handshake to avoid leaked idle connections.
+- Raise dropped, blocked, unmatched, and errored passthrough connection events from debug to warn for better operational visibility.
+
+## 2026-03-16 - 25.11.6 - fix(rustproxy-http,rustproxy-passthrough)
+improve upstream connection cleanup and graceful tunnel shutdown
+
+- Evict pooled HTTP/2 connections when their driver exits and shorten the maximum pooled H2 age to reduce reuse of stale upstream connections.
+- Strip hop-by-hop headers from backend responses before forwarding to HTTP/2 clients to avoid invalid H2 response handling.
+- Replace immediate task aborts in WebSocket and TCP tunnel watchdogs with cancellation-driven graceful shutdown plus timed fallback aborts.
+- Use non-blocking semaphore acquisition in the TCP listener so connection limits do not stall the accept loop for the entire port.
+
+## 2026-03-16 - 25.11.5 - fix(repo)
+no changes to commit

+
 ## 2026-03-15 - 25.11.4 - fix(rustproxy-http)
