8.4.0

Added

• Added method for clients to use default ports for URL scheme.

8.1.2

Fixed

• Fixed issue when connecting to an IP address with HTTPS enabled would result in a ValueError for a mismatch between check_hostname and server_hostname.

8.1.1

Fixed

• Fixed JsonSerializer to return None if a response using Content-Type: application/json is empty instead of raising an error.

8.1.0

Fixed

• Fixed Urllib3HttpNode and RequestsHttpNode to never require a valid certificate chain when using ssl_assert_fingerprint. Instead the internal HTTP client libraries will explicitly disable verifying the certificate chain and instead rely only on the certificate fingerprint for verification.

8.0.1

Fixed

• Fixed AiohttpHttpNode to close TLS connections that aren't properly shutdown by the server instead of leaking them
• Fixed Urllib3HttpNode to respect path_prefix setting in NodeConfig

8.0.0

Added

• Added support for asyncio with AsyncTransport and AiohttpHttpNode
• Added JsonSerializer, NdjsonSerializer
• Added connections_per_node parameter to RequestsHttpNode
• Added support for ssl_assert_fingerprint to RequestsHttpNode
• Added experimental support for pinning non-leaf certificates via ssl_assert_fingerprint when using CPython 3.10+
• Added support for node discovery via "sniffing" using the sniff_callback transport parameter
• Added ability to specify ssl_version via ssl.TLSVersion enum instead of ssl.PROTOCOL_TLSvX for Python 3.7+
• Added elastic_transport.client_utils module to help writing API clients
• Added elastic_transport.debug_logging method to enable all logging for debugging purposes
• Added option to set requests.Session.auth within RequestsHttpNode via NodeConfig._extras['requests.session.auth']

Changed

• Changed *Connection classes to use *Node terminology
• Changed connection_class to node_class
• Changed ConnectionPool to NodePool
• Changed ConnectionSelector to NodeSelector
• Changed NodeSelector(randomize_hosts) parameter to randomize_nodes
• Changed NodeSelector.get_connection() method to get()
• Changed elastic_transport.connection logger name to elastic_transport.node
• Changed Urllib3HttpNode(connections_per_host) parameter to connections_per_node
• Changed return type of BaseNode.perform_request() to NamedTuple(meta=ApiResponseMeta, body=bytes)
• Changed return type of Transport.perform_request() to NamedTuple(meta=ApiResponseMeta, body=Any)
• Changed name of Deserializer into SerializersCollection
• Changed ssl_version to denote the minimum TLS version instead of the only TLS version
• Changed the base class for ApiError to be Exception instead of TransportError. TransportError is now only for errors that occur at the transport layer.
• Changed Urllib3HttpNode to block on new connections when the internal connection pool is exhausted

Removed

• Removed support for Python 2.7
• Removed DummyConnectionPool and EmptyConnectionPool in favor of NodePool.

Fixed

• Fixed a work-around with AiohttpHttpNode where method="HEAD" requests wouldn't mark the internal connection as reusable. This work-around is no longer needed when aiohttp>=3.7.0 is installed.
• Fixed logic for splitting aiohttp.__version__ when determining if HEAD bug is fixed.
