## Release 9.2.0

- Updated the APIs to Elasticsearch [9.2.0](https://www.elastic.co/docs/release-notes/elasticsearch#elasticsearch-9.2.0-release-notes)
- Added the ES|QL query builder [#1462](https://github.com/elastic/elasticsearch-php/pull/1462)

## Release 9.1.0

- Updated the APIs to Elasticsearch [9.1.0](https://www.elastic.co/docs/release-notes/elasticsearch#elasticsearch-9.1.0-release-notes)

## Release 9.0.0

- **Use of PHP 8.1+:** Starting from 9.0.0 the `elasticsearch-php` client requires PHP 8.1+.
- **Compatibility with Elasticsearch 9.0:** All changes and additions to Elasticsearch APIs for its 9.0 release are reflected in this release.
- **Serverless client merged in:** the `elastic/elasticsearch-serverless` client is being deprecated, and its functionality has been merged back into this client. This should have zero impact on the way the client works by default. If an endpoint is available in serverless, the PHP function will contains a `@group serverless` phpdoc attribute.
If you try to use an endpoint that is not available in serverless you will get a `410` HTTP error with a message as follows:
"this endpoint exists but is not available when running in serverless mode".
The 9.0.0 client can recognize that it is communicating with a serverless instance if you are using a URL managed by Elastic (e.g. `*.elastic.cloud`).
If you are using a proxy, the client will be able to recognize that the host is serverless from the first response. Alternatively, you can explicitly indicate that the host is serverless using the `Client::setServerless(true)` function (`false` by default).
- **New transport library with PSR-18 cURL client as default:** we've removed the Guzzle dependency from the client. By default, the built-in cURL-based HTTP client will be used if no other PSR-18 compatible clients are detected. See release [9.0.0](https://github.com/elastic/elastic-transport-php/releases/tag/v9.0.0) of elastic-transport-php.

## Release 8.0.0-alpha

First alpha release of elasticsearch-php 8.0.0.

This major release is a complete new PHP client for Elasticsearch. We build it from scratch!
We tried to reduce the BC breaks as much as possible but there are some (big) differences: 

### Architectural changes:

- we changed the namespace, now everything is under `Elastic\Elasticsearch`
- we used the [elastic-transport-php](https://github.com/elastic/elastic-transport-php) library for HTTP communications;
- we changed the `Exception` model, using the namespace `Elastic\Elasticsearch\Exception`. All the exceptions extends the
  `ElasticsearchException` interface, as in 7.x
- we changed the response type of each endpoints using an [Elasticsearch](src/Response/Elasticsearch.php) response class.
  This class wraps a a [PSR-7](https://www.php-fig.org/psr/psr-7/) response allowing the access of the body response
  as array or object. This means you can access the API response as in 7.x, no BC break here! :angel:
- we changed the `ConnectionPool` in `NodePool`. The `connection` naming was ambigous since the objects are nodes (hosts)

You can have a look at the [BREAKING_CHANGES](BREAKING_CHANGES.md) file for more information.

- Added `ClientBuilder::includePortInHostHeader()` to add the
  `port` in the `Host` header. This fixes [#993](https://github.com/elastic/elasticsearch-php/issues/993).

  With this approach we don't break existing application that convert PHP errors in Exception
  (e.g. using Laravel with issue https://github.com/babenkoivan/scout-elasticsearch-driver/issues/297)
  Using the `@` operator is still possible to intercept the deprecation message using
  a custom error handler.
  [#973](https://github.com/elastic/elasticsearch-php/pull/973)

  the [REST API specification](https://github.com/elastic/elasticsearch/tree/v7.4.2/rest-api-spec/src/main/resources/rest-api-spec/api)

  [#966](https://github.com/elastic/elasticsearch-php/pull/966)
- Fixed the asciidoc [endpoints documentation](https://www.elastic.co/guide/en/elasticsearch/client/php-api/current/ElasticsearchPHP_Endpoints.html) based on the code generation 
  using [Sami](https://github.com/FriendsOfPHP/Sami) project
  [#966](https://github.com/elastic/elasticsearch-php/pull/966)
- All the `experimental` and `beta` APIs are now signed with
  a `@note` tag in the phpdoc section (e.g. [$client->rankEval()](https://github.com/elastic/elasticsearch-php/blob/master/src/Elasticsearch/Client.php)). For more information read the [experimental and beta APIs](docs/experimental-beta-apis.asciidoc)
  section in the documentation.
  [#966](https://github.com/elastic/elasticsearch-php/pull/966)
- Removed `AlreadyExpiredException` since it has been removed
  from Elasticsearch with https://github.com/elastic/elasticsearch/pull/24857
  [#954](https://github.com/elastic/elasticsearch-php/pull/954)

  This fixes the BC break introduced in 7.2.0 and 7.2.1.
  [#947](https://github.com/elastic/elasticsearch-php/pull/)

## Release 7.2.1

- Reintroduced `Elasticsearch\Namespaces\IndicesNamespace::getAliases()` as proxy
  to `IndicesNamespace::getAlias()` to prevent BC breaks. The `getAliases()` is
  marked as deprecated and it will be removed from `elasticsearch-php 8.0`
  [#943](https://github.com/elastic/elasticsearch-php/pull/943)

### Docs
