# Elasticsearch JavaScript Client deprecations
Over time, certain Elastic functionality becomes outdated and is replaced or removed. To help with the transition, Elastic deprecates functionality for a period before removal, giving you time to update your applications.
Review the deprecated functionality for the Elasticsearch JavaScript Client. While deprecations have no immediate impact, we strongly encourage you update your implementation after you upgrade. To learn how to upgrade, check out [Upgrade](https://docs-v3-preview.elastic.dev/elastic/docs-builder/docs/2904/deploy-manage/upgrade).

## 9.0.0

_No deprecations_
