 # Changelog
 
+## 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
+
+- Propagate connection activity tracking through HTTP/1, HTTP/2, and WebSocket forwarding so active request and response body streams do not trigger the idle watchdog.
+- Update CountingBody to refresh connection activity timestamps while data frames are polled during uploads and downloads.
+- Increase pooled HTTP/2 max age and set explicit HTTP/2 connection window sizes to improve long-lived streaming behavior.
+
 ## 2026-03-15 - 25.11.0 - feat(rustproxy-http)
 add HTTP/2 Extended CONNECT WebSocket proxy support
