Shield and Watcher 2.0.0-beta2 releases introduce several new features and improvements for testing purposes, with Document and Field Level Access Control now a first-class feature in Shield, allowing more precise data security management by defining document and field accessibility per role. Additionally, Shield supports User Impersonation, enabling users to execute requests on behalf of others when authentication is managed outside Elasticsearch, and allows custom implementation of authentication realms. Watcher enhances its functionality by allowing users to deactivate watches during system maintenance and adds new communication actions via HipChat and Slack for templated notifications. These updates also include bug fixes and infrastructure enhancements, with further details available in the release notes and forums.
