+## NOTICE: node12 deprecation warning
+GitHub actions has recently started throwing warning messages regarding the deprecation of Node 12. If you would like to stop seeing this warning, configure your action to use `aws-actions/configure-aws-credentials@v1-node16`. Both the `v1` branch and the `v1-node16` branch will receive the same updates moving forward. See [this issue](https://github.com/aws-actions/configure-aws-credentials/issues/489) for more information on this topic.
