 - Bumps `github.com/aws/aws-sdk-go-v2/config` from 1.25.11 to 1.27.0
 ### Added
 - Added new struct fields introduced by opensearch 2.12 ([#482](https://github.com/opensearch-project/opensearch-go/pull/482))
+- Adds initial admin password environment variable and CI changes to support 2.12.0 release ([#449](https://github.com/opensearch-project/opensearch-go/pull/449))
 ### Changed
 - Changed field opensearch_version of type NodesInfoPlugin to json.RawMessage as opensearch 3.0.0 uses an array instead of string ([#482](https://github.com/opensearch-project/opensearch-go/pull/482))
