 # Changelog
 
+## 2026-04-26 - 4.17.0 - feat(core)
+add performance profiles, transport observability, and edge stream budget controls
+
+- introduce configurable performance profiles and effective per-edge limits for stream concurrency, flow-control windows, and QUIC datagram buffers
+- expose hub-side edge status for transport mode, fallback usage, flow-control, queue depths, traffic counters, and UDP session metrics
+- enforce edge-side stream admission limits before spawning client tunnel tasks and make TCP/TLS window sizing honor edge memory budgets under high concurrency
+- increase QUIC datagram receive buffer configurability and improve hub-side QUIC UDP session tracking and idle pruning
+- update hub APIs and documentation to support performance configuration and clarify quicWithFallback as the default edge transport
+
+## 2026-04-26 - 4.16.0 - feat(performance)
+add remote ingress performance controls and runtime observability
+
+- add performance profiles and configurable stream/window budgets for hub and edge connections
+- expose per-edge transport, flow-control, queue, traffic, and UDP status from hub status
+- enforce edge-side stream admission before spawning client tunnel tasks
+- make TCP/TLS flow control honor an edge-level memory budget under high concurrency
+- increase QUIC datagram receive buffers and prune idle hub-side QUIC UDP sessions
+
 ## 2026-03-27 - 4.15.3 - fix(core)
 harden UDP session handling, QUIC control message validation, and bridge process cleanup
