## 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.

- Generated the new endpoints for Elasticsearch 7.6.0
  [be31f31](https://github.com/elastic/elasticsearch-php/commit/be31f317af704f333b43bbcc7c01ddc7c91ec6f8)

  [75e0888](https://github.com/elastic/elasticsearch-php/commit/125594b40d167ef1509b3ee49a3f93426390c426)
- Added `ClientBuilder::includePortInHostHeader()` to add the
  `port` in the `Host` header. This fixes [#993](https://github.com/elastic/elasticsearch-php/issues/993).
  By default the `port` is not included in the `Host` header.

  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)
  of Elasticsearch. This tool is available in `util/GenerateEndpoints.php`.
  [#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)

## Release 7.3.0

  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

- Fixed missing put mapping code snippet in code examples
  [#938](https://github.com/elastic/elasticsearch-php/pull/938)
