9.3.0 (2026-02-04)

⚠ BREAKING CHANGES

• Upgrade Go version from 1.23 to 1.24 (#1137)
• API: API methods and request fields that previously accepted a single string for resource identifiers (e.g., indices, names, IDs, routing, features) now require []string. Corresponding WithX helpers now accept variadic arguments (...string).
• API: All ExpandWildcards request fields were changed from string to []string, and WithExpandWildcards helpers now accept variadic arguments (...string).
• API: Routing parameters across document, search, and multi-document APIs were changed from string to []string, and related WithRouting helpers now accept variadic arguments (...string).
• API: Duration-based parameters previously expressed as string now use time.Duration (e.g., KeepAlive, Interval, BucketSpan). Call sites must pass time.Duration values.
• API: ML APIs using interface{} for start/end time parameters now require string values, removing support for arbitrary types.
• API: Several top-level API methods now require []string instead of string for path parameters that support multiple resources (e.g., indices, templates, data streams, transforms, repositories, privileges).
• API: MonitoringBulk was refactored: DocumentType support was removed, Interval is now time.Duration, and required parameters were added explicitly to the method signature.
• API: Some WithX functional options changed between single-value and variadic forms to match API behaviour. Existing option usage may require updates.
• API: Request struct fields were updated to reflect REST API semantics, including changes from string to []string and removal of deprecated fields. Direct struct initialization may require changes.

Features

• API: Introduce strong typing for duration values (3c657da)
• API: Support multi-value resource parameters (3c657da)
• API: Support multiple resources per request (3c657da)
• API: Update APIs to 9.3.0 (3c657da)
• Expose FlushedMs metric in BulkIndexer (#1191) (d67d0be)
• Typed API: Add DenseVectorF32 and DenseVectorBytes types, improving indexing performance of dense vectors by up to 3x when used instead of a float32 array (f543b82)
• Typed API: Update TypedAPI to latest elasticsearch-specification 9.3.0 (f543b82)
• Upgrade Go version from 1.23 to 1.24 (#1137) (05f15eb)

Bug Fixes

• API: Align routing parameters with REST API (3c657da)
• API: Correct functional option cardinality (3c657da)
