+## Feature Flags
+
+### useGOMEMLIMIT
+
+A new flag, `useGOMEMLIMIT` has been added that allows specifying whether or not the chart should use the `GOMEMLIMIT` environment variable or the Memory Ballast Extension.
+When enabled, the chart will remove the Memory Ballast Extension from the collector's configuration AND will setup a `GOMEMLIMIT` environment variable that is set to 80%
+of the configured `resources.limits.memory`.  If no `resources.limits.memory` are set when `useGOMEMLIMIT` is enabled then a `GOMEMLIMIT` environment variable WILL NOT be
+created but the Memory Ballast Extension will still be removed.
+
+If you are not interested in using `GOMEMLIMIT` then this change does not affect you.  But, 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.

 ## 0.69.3 to 0.70.0
 
 The following deprecated fields have been removed.  Please use the new values:
