8.0.0 (2022-02-10)

edit

Added

edit
  • Added the top-level .options() method to Elasticsearch and AsyncElasticsearch for modifying transport options.

  • 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.

Changed

edit
  • 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.

Removed

edit

  • 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

  • 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
