 ## Security Considerations
 
-OpenTelemetry Collector recommends to bind receivers' servers to addresses that limit connections to authorized users. This is typically not needed in containerized environments, although the Open Telemetry Collector logs the following:
-```
-Using the 0.0.0.0 address exposes this server to every network interface, which may facilitate Denial of Service attacks
-```
+OpenTelemetry Collector recommends to bind receivers' servers to addresses that limit connections to authorized users.
+For this reason, by default the chart binds all the Collector's endpoints to the pod's IP.
+
 More info is available in the [Security Best Practices docummentation](https://github.com/open-telemetry/opentelemetry-collector/blob/main/docs/security-best-practices.md#safeguards-against-denial-of-service-attacks)
 
 Some care must be taken when using `hostNetwork: true`, as then OpenTelemetry Collector will listen on all the addresses in the host network namespace.

 # Upgrade guidelines
 
+## 0.45.0 to 0.46.0
+
+[Update Collector Endpoints to use Pod IP Instead of 0.0.0.0](https://github.com/open-telemetry/opentelemetry-helm-charts/pull/603)
+
+The [Collector's security guidelines were updated](https://github.com/open-telemetry/opentelemetry-collector/pull/6959) to include containerized environments when discussing safeguards against denial of service attacks.
+To be in compliance with the Collector's security best practices the chart has been updated to use the Collector's pod IP in place of `0.0.0.0`.
+
+The chart will continue to allow complete configuration of the Collector via the `config` field in the values.yaml.  If pod IP does not suite your needs you can use `config` to set something different.
+
+See [Security Best Practices docummentation](https://github.com/open-telemetry/opentelemetry-collector/blob/main/docs/security-best-practices.md#safeguards-against-denial-of-service-attacks) for more details.
