 # Elastic Ruby connectors

+> [!IMPORTANT]
+> _**Enterprise Search will be discontinued in 9.0.**_
+>
+> Starting with Elastic version 9.0, we're deprecating the standalone Enterprise Search product with its included features and functionalities (including [Workplace Search](https://www.elastic.co/guide/en/workplace-search/8.x/index.html) and [App Search](https://www.elastic.co/guide/en/app-search/8.x/index.html)). They remain supported in their current form in version 8.x and will only receive security upgrades and fixes. Workplace Search Connector Packages will continue to be supported in their current form throughout 8.x versions, according to our EOL policy: https://www.elastic.co/support/eol.
+> We recommend transitioning to our actively developed [Elastic Stack](https://www.elastic.co/elastic-stack) tools for your search use cases. However, if you're still using any Enterprise Search products, we recommend using the latest stable release.
+>
+> Here are some useful links with more information:

+> * Migrating to 9.x from Enterprise Search 8.x versions: https://www.elastic.co/guide/en/enterprise-search/current/upgrading-to-9-x.html
