+  This change is being made to ensure sensitive information contained in logs are never logged inadvertently.
+  This change is a breaking change because it may change user expectations. However, it should require
+  no action on the part of the user unless they are relying on logs from a few specific error cases.
+
+# If your change doesn't affect end users or the exported elements of any package,
+# you should instead start your pull request title with [chore] or use the "Skip Changelog" label.
+# Optional: The change log or logs in which this entry should be included.
+# e.g. '[user]' or '[user, api]'
+# Include 'user' if the change is relevant to end users.
+# Include 'api' if there is a change to a library API.
+# Default: '[user]'
