# Elasticsearch Java Client 9.5.0
Discover what changed in the 9.5.0 version of the Java client.

## Breaking changes

This version presents many updates to existing fields that were wrongly mapped, or incomplete. Here is the complete list of changes:
<dropdown title="From single value to union type">
  Some fields have been remapped to tagged unions to correctly represent that they can accept more than one shape.
  - elasticsearch._types.mapping.DocValuesPropertyBase
    - `docValues`: modified from `Boolean` to `elasticsearch._types.mapping.DocValues`, now a union of a simple `Boolean` (`enabled`) or a `DocValuesConfig` object (`config`)
  - elasticsearch.inference.RerankRequest
    - `input`: modified from `List<String>` to `elasticsearch.inference.rerank.RerankInput`, now a union of a list of strings (`string`) or a list of objects (`object`)
  - `query`: modified from `String` to `elasticsearch.inference.rerank.RerankQuery`, now a union of a simple string (`string`) or an object (`object`)
</dropdown>

<dropdown title="Snapshot source-only repository remapping">
  `SourceOnlyRepositorySettings` is now a tagged union discriminated by `delegate_type`: choosing a delegate type (`azure`, `gcs`, `url`, `s3` or `fs`) makes its own settings available.
  - elasticsearch.snapshot.SourceOnlyRepositorySettings: now a tagged union (`azure`, `gcs`, `url`, `s3`, `fs`)
  For example, to register a source-only repository delegating to a shared file system (`fs`):
  ```java
  esClient.snapshot().createRepository(r -> r
      .name("my_src_only_repository")
      .repository(repo -> repo
          .source(source -> source
              .settings(settings -> settings
                  .fs(fs -> fs
                      .location("my_backup_repository")
                  )
              )
          )
      )
  );
  ```
</dropdown>

<dropdown title="Watcher fixes">
  Most of the watcher types were outdated and wrongly mapped. The following changes bring them in line with the actual API:
  - elasticsearch.watcher.ExecutionResultCondition
    - `status`: modified from `elasticsearch.watcher.ActionStatusOptions` to `elasticsearch.watcher.ExecutionResultStatus`
  - elasticsearch.watcher.ExecutionResultInput
    - `status`: modified from `elasticsearch.watcher.ActionStatusOptions` to `elasticsearch.watcher.ExecutionResultStatus`
  - elasticsearch.watcher.IndexResult
    - `response`: modified from `elasticsearch.watcher.IndexResultSummary` to `List<IndexResultSummary>`. `IndexResult` is now a union that can hold either the `response` of an executed index action or the `request` that would have run when the action is simulated
  - elasticsearch.watcher.IndexResultSummary
    - `created`: modified from `boolean` to `Boolean`, now optional
  - `version`: modified from `long` to `Long`, now optional
  - elasticsearch.watcher.SearchInputRequestBody: **removed**
  - elasticsearch.watcher.SearchInputRequestDefinition
    - `body`: modified from `elasticsearch.watcher.SearchInputRequestBody` to `elasticsearch.core.search.SearchRequestBody`
</dropdown>

<dropdown title="Other changes">
  - elasticsearch._types.analysis.SynonymTokenFilterBase
    - `synonymsSet`: modified from `String` to `List<String>`, now required
  - elasticsearch.cluster.stats.DenseVectorOffHeapStats
    - `totalCenifSizeBytes`: renamed to `totalCenivfSizeBytes`
  - `totalCenifSize`: renamed to `totalCenivfSize`
  - elasticsearch.indices.stats.ShardStats
    - `indices`: modified from `elasticsearch.indices.stats.IndicesStats` to `Map<String, ShardStats>`, now required
  - elasticsearch.inference.EmbeddingContentObject
    - `content`: modified from `elasticsearch.inference.EmbeddingContentObjectContents` to `List<EmbeddingContentObjectItem>`
  - elasticsearch.inference.EmbeddingContentObjectContents: **removed**
  - elasticsearch.security.Role
    - `indices`: modified from `List<IndicesPrivileges>` to `List<IndicesPrivilegesRead>`
  - elasticsearch._types.mapping.SourceField
    - `compress`: **removed**
  - `compressThreshold`: **removed**
</dropdown>
