## What's Changed

Initial 9.5.x release.

> [!WARNING]
> This release regenerates the client against the Elasticsearch 9.5 specification and contains breaking changes. Please review the list below before upgrading.

* Regenerate client against the Elasticsearch 9.5 specification by @flobernd in https://github.com/elastic/elasticsearch-net/pull/8930 and https://github.com/elastic/elasticsearch-net/pull/8944
  * New experimental `client.Encryption.Reset` endpoint, plus a `ProjectEncryptionKey` indicator on the health report
  * New experimental ES|QL data federation APIs: `PutDataSource` / `GetDataSource` / `DeleteDataSource` and `PutDataset` / `GetDataset` / `DeleteDataset`, with the supporting `ESQLDataSource`, `ESQLDataset` and `DatasetMapping` types
  * New experimental Inference region policy APIs: `PutRegionPolicy` / `GetRegionPolicy` / `DeleteRegionPolicy`
  * New `_slice` routing parameter (`RouteSlice`) across the search, get, index, delete, update and bulk APIs, as well as on the multi-search header and the reindex destination
  * `FrequentItemSets` aggregations now round-trip correctly. The generated variant used an empty discriminator where the converter expected `frequent_item_sets`, so the property always read back as `null`
  * Role-template queries in index privileges now deserialize to `RoleTemplateQuery`. Previously any object-shaped query was unconditionally read as a regular `QueryDsl.Query`
  * `SpanGap` and `RoleMappingRule.Field` variant accessors now return `null` instead of a default `KeyValuePair` when the union holds a different variant
  * New enum members: `EmbeddingContentType.Audio` / `.Pdf` / `.Video`, `AnthropicTaskType.ChatCompletion`, `OpenAITaskType.Embedding`, and the `ClusterPrivilege.ManageReindex` / `.MonitorReindex` values
  * **Breaking (mapping)**: `DocValues` on 32 property types changes from `bool?` to `Union<bool, DocValuesConfig>?` to carry the new `doc_values.multi_value` setting. The parameterless `DocValues()` descriptor overload is gone, and reading the property into a `bool?` no longer compiles. `SourceField.Compress` and `CompressThreshold` are removed, and `TextIndexPrefixes.MinChars` / `MaxChars` become optional (`int?`), dropping the two-argument constructor
  * **Breaking (ES|QL)**: the named-parameter arm of `Params` on `EsqlQuery` and `AsyncQuery` changes from `KeyValuePair<string, ICollection<FieldValue>>` to `KeyValuePair<string, Union<ICollection<FieldValue>, ClassifiedNamedParameter>>`, which affects every existing named-parameter call site. Both requests also gain a `Settings` body property
  * **Breaking (inference)**: `Rerank` now accepts the expanded multimodal request format, so `Input` becomes `Union<ICollection<string>, ICollection<RerankInputObject>>`, `Query` becomes `Union<string, RerankInputObject>`, and the `Input(params string[])` overload is removed. `EmbeddingContentObject.Content` becomes `ICollection<EmbeddingContentObjectItem>` and `EmbeddingContentObjectContents` is gone, `OpenAIServiceSettings.ApiKey` is now optional, and `JinaAIServiceSettings.ElementType` is renamed to `EmbeddingType`
  * **Breaking (snapshot)**: `SourceOnlyRepositorySettings` is replaced by the `ISourceOnlyRepositorySettings` variant family with per-backend settings types, constructed through `SourceOnlyRepositorySettingsFactory` (`ForAzure`, `ForGcs`, `ForReadOnlyUrl`, `ForS3`, `ForSharedFileSystem`). `SourceOnlyRepository.Settings` now takes the interface, and its descriptor overloads are replaced by a factory callback
  * **Breaking (security)**: `RoleInfo.Indices` changes from `IndicesPrivileges` to `IndicesPrivilegesRead`, and role definitions gain `DataSourcePrivileges`
  * **Breaking (stats)**: `GetStats.Time` is renamed to `GetTime`, `ShardStats.Indices` becomes a dictionary of `ShardStats`, the `DenseVectorOffHeapStats.TotalCenifSize` typo is corrected to `TotalCenivfSize`, and newly required members change the positional constructors of `IndexingStats`, `SearchStats`, `FlushStats`, `MappingStats` and `MachineLearning.Defaults`
* Make custom JSON converters safe for multi-segment readers by @flobernd in https://github.com/elastic/elasticsearch-net/pull/8923
  * The hand-written date, duration, stringified and fractional numeric converters no longer fail when the `Utf8JsonReader` is constructed over a multi-segment `ReadOnlySequence<byte>`, which unblocks sequence-based deserializers such as a streaming reader over a `PipeReader`
  * The existing single-segment typed deserialization path is unchanged

## New Contributors
* @charlotte-hoblik made their first contribution in https://github.com/elastic/elasticsearch-net/pull/8901

9.5.1

> [!WARNING]
> This release contains breaking changes in generated types. Please review the breaking changes listed below before upgrading.

## What's Changed

* Regenerate client by @flobernd in https://github.com/elastic/elasticsearch-net/pull/8957 and https://github.com/elastic/elasticsearch-net/pull/8981
  * Transform destinations now accept `aliases`, each with an optional `move_on_creation` flag, through the new `DestinationAlias` type.
  * Request converter sources regenerated to emit the full client invocation.
  * **Breaking**: `KnnRetriever.NumCandidates` is now optional (`int?` instead of `required int`), following the spec change that made `num_candidates` optional on the kNN retriever. The `[SetsRequiredMembers]` constructor no longer takes a `numCandidates` argument.
  * **Breaking**: `TransformSummary.Dest` and `UpdateTransformResponse.Dest` now use `Elastic.Clients.Elasticsearch.TransformManagement.Destination` instead of `Elastic.Clients.Elasticsearch.Core.Reindex.Destination`.
* Restore delegate caching in IdResolver by @fresh55 in https://github.com/elastic/elasticsearch-net/pull/8973
  * The getter delegate was only cached when resolution failed, so it was rebuilt on every successful call.
  * 100k resolves of the same type improve from 64 ms / 55.2 MB to 3.5 ms / 40 bytes. Partially addresses (#7664).
