And to @tblyler for fixing a very subtle memory leak in the `BulkIndexer`. #797

# 8.12.1

* Fix: ticker memory leak in bulk indexer due to internal flush call resetting the ticker. #797
* Fix: Scroll now uses the body to pass the scroll_id. #785
* Add: generated UnmarshalJSON for Requests to allow injecting payloads using aliases.
* Fix: `put_synonym_rule` was not working due to a type issue in the [Elasticsearch API Specification](https://github.com/elastic/elasticsearch-specification/pull/2407).

## Client

### Golang version

The client now requires Golang version 1.20

### OpenTelemetry

The client now provides OpenTelemetry integration. This integration can be enabled in the config using the `elasticsearch.NewOpenTelemetryInstrumentation`.
Once set up, the provided `context` will be used to record spans with useful information about the request being made to the server.

More about what you can expect in the [Semantic Conventions for Elasticsearch](https://opentelemetry.io/docs/specs/semconv/database/elasticsearch/).

## Typed API

Following multiple feedbacks we decided to remove the builder API for the type tree.

In its place, work has started to further simplify the type tree by removing redundant type aliases. The API also now comes with a helper package named `some` that allows to call for inline pointers on primitive types.

In addition, a bug was fixed preventing the use of wildcards in index names, and enums are now extensible by default.

The Typed API remains in `alpha` stage while its development continues.

# 8.4.0

## API

* `get`, `mget` and `search` added `force_synthetic_source`: Should this request force synthetic _source? Use this to test if the mapping supports synthetic _source and to get a sense of the worst case performance. Fetches with this enabled will be slower the enabling synthetic source natively in the index.
* `ML.StartTrainedModelDeployment` added `cache_size`: A byte-size value for configuring the inference cache size. For example, 20mb.
* `Snapshot.Get` added `sort`, `size`, `order`, `from_sort_value`, `after`, `offset` and `slm_policy_filter`. More on these in the [documentation](https://www.elastic.co/guide/en/elasticsearch/reference/8.4/get-snapshot-api.html).

**New API**

* `Security.UpdateAPIKey` [documentation](https://www.elastic.co/guide/en/elasticsearch/reference/8.4/security-api-update-api-key.html).

## Typed API

As highlighted in the release not for the 8.4.0-alpha.1, this release marks the beginning of the newly arrived `TypedClient`.

This new API is still in `alpha` stage and will be release alongside the existing `esapi`.

A few examples of standard use-cases can be found in the [TypedAPI section of the documentation](https://www.elastic.co/guide/en/elasticsearch/client/go-api/master/typedapi.html).

# 8.4.0-alpha.2

This second prerelease of the 8.4.0 updates the API for the client and fixes the serialization for types using [additional properties](https://github.com/elastic/elasticsearch-specification/blob/main/docs/behaviors.md#additionalproperties--additionalproperty).

# 8.4.0-alpha.1

This prerelease introduces a new typed API generated from the [elasticsearch-specification](https://github.com/elastic/elasticsearch-specification). This generation from the common specification allows us to provide a complete API which uses an exhaustive hierarchy of types  reflecting the possibilities given by Elasticsearch.

This new API is the next iteration of the Go client for Elasticsearch, it now lives alongside the existing API, it is in `alpha` state and will gain features over time and releases.

## What's new

The `TypedClient` is built around a fluent builder for easier request creation and a collection of structures and helpers that mimics as closely as possible the Elasticsearch JSON API.

As a first example, here is a search request:
```go
cfg := elasticsearch.Config{
// Define your configuration
}
es, _ := elasticsearch.NewTypedClient(cfg)
res, err := es.Search().
Index("index_name").
Request(&search.Request{
Query: &types.QueryContainer{
Match: map[types.Field]types.MatchQuery{
"name": {Query: "Foo"},
},
},
},
).Do(context.Background())
```

The `Request` uses the structures found in the `typedapi/types` package which will lead you along the possibilities. A builder for each structure that allows easier access and declaration is also provided.

More on the specifics and a few examples of standard use-cases can be found in the [TypedAPI section of the documentation](https://www.elastic.co/guide/en/elasticsearch/client/go-api/master/typedapi.html).

## Limitations

While most of the endpoints are covered, a few points are still being worked on and will be part of future releases:

* NDJSON endpoints: `bulk`, `msearch`, `msearch_template`, `ML.post_data`, `find_structure`, to name a few.
* Response and Errors structures with deserialization.

## Transport & config

While being different, the new API uses all the existing layers that were built so far, `elastic-transport-go` remains the preferred transport and all your configuration and credentials applies, same as before.

## Feedback

Feedback is very welcome, play with it, use it, let us know what you think!
