 Depending on the progress made in [Issue 891](https://github.com/open-telemetry/opentelemetry-helm-charts/issues/891),
 the use of `GOMEMLIMIT` may completely replace the Memory Ballast Extension in the future.
 
+## 0.78.2 to 0.78.3
+
+[Update Health Check Extension's endpoints to use Pod IP Instead of 0.0.0.0](https://github.com/open-telemetry/opentelemetry-helm-charts/pull/1012)
+
+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.
+
 ## 0.75.1 to 0.76.0
 
 Enable the `useGOMEMLIMIT` feature flag by default. This means by default the chart now does not use the Memory Ballast Extension and any custom configuraiton applied to the Memory Ballast Extension is ignored.
