 ## Unreleased
 * **Logging**
+  * [ANNOUNCEMENT] The [OpenDistro for Elasticsearch (ODFE) project](https://opendistro.github.io/for-elasticsearch/) reached end-of-line in May of 2022 and our project moved to
+  OpenSearch shorly thereafter.  This release removes all remaining support for ODFE; including support for migration from ODFE
+  and ability to use utility scripts (e.g. change_internal_password.sh) with ealier ODFE-backed deployments.  
+  * [REMOVAL] Remove support for migrating from an earlier deployment which included ODFE.
+  * [REMOVAL] Remove support for the `LOG_SEARCH_BACKEND` environment variable.  Scripts will terminate with an ERROR message if
+  this environment variable is detected.
   * [CHANGE] The Fluent Bit Deployment used for Kubernetes Event collection can now be integrated into the
 SAS Viya Workload node placement strategy.
   * [CHANGE] An obsolete configuration file related to the Event Router has been removed from the repo.
