Migration guide
editMigration guide
editThis section describes the breaking changes and deprecations introduced in this release and previous minor versions.
As Elasticsearch introduces new features and improves existing ones, the changes sometimes make older settings, APIs, and parameters obsolete. The obsolete functionality is typically deprecated in a minor release and removed in the subsequent major release. This enables applications to continue working unchanged across most minor version upgrades. Breaking changes introduced in minor releases are generally limited to critical security fixes and bug fixes that correct unintended behavior.
To get the most out of Elasticsearch and facilitate future upgrades, we strongly encourage migrating away from using deprecated functionality as soon as possible.
To give you insight into what deprecated features you’re using, Elasticsearch:
-
Returns a
Warn
HTTP header whenever you submit a request that uses deprecated functionality. - Logs deprecation warnings when deprecated functionality is used.
- Provides a deprecation info API that scans a cluster’s configuration and mappings for deprecated functionality.
