+no changes to commit
+
+
+## 2026-03-15 - 25.11.2 - fix(rustproxy-http)
+avoid reusing HTTP/1 senders during streaming responses and relax HTTP/2 keep-alive timeouts
+
+- Stop returning HTTP/1 senders to the connection pool before upstream response bodies finish streaming to prevent unsafe reuse on active connections.
+- Increase HTTP/2 keep-alive timeout from 5 seconds to 30 seconds in proxy connection builders to better support longer-lived backend streams.
+- Improves reliability for large streaming payloads and backend fallback request handling.
+
 ## 2026-03-15 - 25.11.1 - fix(rustproxy-http)
 keep connection idle tracking alive during streaming and tune HTTP/2 connection lifetimes
