+## 2024.10.0
+### Bug Fixes
+- We fixed a bug related to `--grace-period`. Tunnels that use QUIC as transport weren't abiding by this waiting period before forcefully closing the connections to the edge. From now on, both QUIC and HTTP2 tunnels will wait for either the grace period to end (defaults to 30 seconds) or until the last in-flight request is handled. Users that wish to maintain the previous behavior should set `--grace-period` to 0 if `--protocol` is set to `quic`. This will force `cloudflared` to shutdown as soon as either SIGTERM or SIGINT is received.
+
+## 2024.2.1
+### Notices
+- Starting from this version, tunnel diagnostics will be enabled by default. This will allow the engineering team to remotely get diagnostics from cloudflared during debug activities. Users still have the capability to opt-out of this feature by defining `--management-diagnostics=false` (or env `TUNNEL_MANAGEMENT_DIAGNOSTICS`).
+
+## 2023.9.0
+### Notices
+- The `warp-routing` `enabled: boolean` flag is no longer supported in the configuration file. Warp Routing traffic (eg TCP, UDP, ICMP) traffic is proxied to cloudflared if routes to the target tunnel are configured. This change does not affect remotely managed tunnels, but for locally managed tunnels, users that might be relying on this feature flag to block traffic should instead guarantee that tunnel has no Private Routes configured for the tunnel.
 ## 2023.7.0
 ### New Features
 - You can now enable additional diagnostics over the management.argotunnel.com service for your active cloudflared connectors via a new runtime flag `--management-diagnostics` (or env `TUNNEL_MANAGEMENT_DIAGNOSTICS`). This feature is provided as opt-in and requires the flag to enable. Endpoints such as /metrics provides your prometheus metrics endpoint another mechanism to be reached. Additionally /debug/pprof/(goroutine|heap) are also introduced to allow for remotely retrieving active pprof information from a running cloudflared connector.
