Upgrading to Enterprise Search 8.1.0? See Upgrading and migrating.

The latest enhancements to the Elastic App Search web crawler ensure faster and more efficient content ingestion, with additional troubleshooting capabilities.
A connector for SharePoint Server is available in beta. Install the connector to enable aggregation of on-premises SharePoint Server (2013, 2016 and 2019) content into Workplace Search.
Enterprise Search monitoring information is available in Kibana Monitoring when metrics and logs are sent to a monitoring deployment.
Search performance is improved for grouping on high-cardinality fields.
The project has been switched to JRuby 9.3.3.0 with better support for newer Java versions and full native support for M1 Macs.
Elasticsearch Native Realm users are no longer required to have an email address in order to be added to Enterprise Search.
Download diagnostics button appears when the Check diagnostic bundle for details error message is returned for a content source.

Authorization failures in API requests return 403 as HTTP status code instead of 401.
Potential migration failure related to role mappings is fixed when upgrading from 7.12 to 7.17 and then to 8.0.
Self-monitoring functionality did not work properly in cases where Enterprise Search HTTP port was blocked by a firewall.
Non-owner/admins are no longer shown schema actions they cannot access.
ServiceNow can no longer have a configured Base URL host of localhost. Redirects to any host other than the configured Base URL host are no longer possible.

App Search users with dev and editor roles do not have access to the web crawler.
