➔ go-elasticsearch v9.3.5 - BulkIndexer Routing Param Fix
Elastic released go-elasticsearch v9.3.5 on June 22, 2026. This is a focused patch for esutil.BulkIndexer: it stops sending an empty routing query param when no routing value is set. If you are checking what changed in go-elasticsearch v9.3.5, this release is about bulk indexing request correctness, not a broad client update.
