 # Changelog
 
+## 2026-03-16 - 4.6.1 - fix(remoteingress-core)
+avoid spurious tunnel disconnect events and increase control channel capacity
+
+- Emit TunnelDisconnected only after an established connection is actually lost, preventing false disconnect events during failed reconnect attempts.
+- Increase edge and hub control-channel buffer sizes from 64 to 256 to better prioritize control frames under load.
+
 ## 2026-03-16 - 4.6.0 - feat(remoteingress-core)
 add adaptive per-stream flow control based on active stream counts
