The announcement details the release of the first release candidate for a new Elasticsearch JavaScript client, following a comprehensive refactoring process aimed at resolving versioning issues and improving user experience. The new client will be released under the @elastic npm organization and promises numerous enhancements, such as modern syntax, improved performance, and TypeScript support, offering a more intuitive and consistent developer experience. The package reorganization involves publishing a new scoped package and transforming the existing package into a pointer to the latest version, allowing for a smoother transition for users. The refactoring results in breaking changes, such as the removal of browser support and the introduction of new error handling mechanisms, necessitating code adjustments for users of the previous client version. The release aims to align with the final release of Elasticsearch 7.0, and users are encouraged to report bugs and propose features to further refine the client.
