What is the current version of Elasticsearch?

release of Elasticsearch 7.4. 0, based on Lucene 8.2. 0. Version 7.4 is the **latest stable **release of Elasticsearch and is now available for deployment via **Elasticsearch Service on Elastic Cloud

In Dockerfile for both VueStorefrontApi and StorefrontApi we have 7.3.2 version of Elasticsearch. So I guess it is the newest tested version
