[discrete]
[[rn-8-0-0]]

[discrete]
==== Added

* Added the top-level `.options()` method to `Elasticsearch` and `AsyncElasticsearch` for modifying transport options.
* Added parameters corresponding to JSON request body fields for all APIs
* Added `basic_auth` parameter for specifying username and password authentication
* Added `bearer_auth` parameter for specifying an HTTP bearer token or service token
* Added the `meta` property to `ApiError` to access the HTTP response metadata of an error.
* Added a check that a compatible version of the `elastic-transport` package is installed.

[discrete]
==== Changed

* Changed the transport layer to use the `elastic-transport` package
* Changed user-defined `body` parameters to have semantic names (e.g `index(document={...})` instead of `index(body={...})`).
* Changed responses to be objects with two properties, `meta` for response metadata (HTTP status, headers, node, etc) and `body` for a typed body.
* Changed `AsyncElasticsearch` to always be available, regardless of whether `aiohttp` is installed
* Changed exception hierarchy, the major change is a new exception `ApiError` which differentiates between an error that's raised from the transport layer (previously `elasticsearch.exceptions.TransportError`, now `elastic_transport.TransportError`) and one raised from the API layer
* Changed the name of `JSONSerializer` to `JsonSerializer` for consistency with other serializer names. Added an alias to the old name for backwards compatibility
* Changed the default mimetypes (`application/json`) to instead use compatibility mimetypes (`application/vnd.elasticsearch+json`) which always request for responses compatibility with version 8.x.

[discrete]
==== Removed

* Removed support for Python 2.7 and Python 3.5, the library now supports only Python 3.6+
* Removed the `elasticsearch.connection` module as all functionality has been moved to the `elastic-transport` package
* Removed the default URL of `http://localhost:9200` due to Elasticsearch 8.0 default configuration being `https://localhost:9200`.
  The client's connection to Elasticsearch now must be specified with scheme, host, and port or with the `cloud_id` parameter
* Removed the ability to use positional arguments with API methods. Going forward all API parameters must be keyword-only parameters
* Removed the `doc_type`, `include_type_name`, and `copy_settings` parameters from many document and index APIs

[discrete]
==== Deprecated

* Deprecated the `body` and `params` parameters on all APIs
* Deprecated setting transport options `http_auth`, `api_key`, `ignore`, `request_timeout`, `headers`, and `opaque_id`
  All of these settings should instead be set via the `.options()` method
* Deprecated the `elasticsearch.transport` and `elasticsearch.client` modules. These modules will be removed in a future version
