March 14, 2019, marks the release of the third iteration of Elastic App Search beta, known as Beta3, which introduces several new features and improvements. Users can now configure a mailer for sending invitations and create a compressed diagnostic bundle for troubleshooting. Noteworthy enhancements include the removal of the sample Engine, improved indexing performance, and configuration management through an appsearch.yml file. Additionally, multi-query curations have been updated to lift restrictions on active curated queries. The release encourages users of previous betas to upgrade and invites feedback as the product moves closer to general availability, with a call for new users to experience the free test drive of Elastic App Search.
