Elasticsearch 7.7 Update by March 29, 2023 comment

AWS currently does not have an End of Life policy for OpenSearch/ElasticSearch versions. However, we always recommend our customers to upgrade to the latest version to benefit from new features, bug fixes and performance improvements. As for the end of life, if and when AWS will plan to end support for a specific version, AWS will provide initiation via emails regarding the same and also provide enough notice period (12-18 months) for customers to be able to upgrade their domains.
