Sourced from gql's releases.

v4.0.0

Breaking Changes

• Change transports prototype using GraphQLRequest (#551)
• Using GraphQLRequest instead of DocumentNode for gql, execute, subscribe methods (#556): This is a big change:
  • the gql and dsl_gql methods will now return a GraphQLRequest instead of a Document Node a GraphQLRequest is an object containing the document and optional variable_values and operation_name
  • ALL the execute and subscribe methods now receive a GraphQLRequest as main argument instead of a DocumentNode, variable_values and operation_name arguments
  • The old method of sending variable_values as an argument of execute or subscribe still works but is deprecated See https://gql.readthedocs.io/en/latest/usage/variables.html for the new syntax.
• Fix subscription task cancel exception swallow (#548): Previously if a task was cancelled while a subscription task was active, the asyncio.CancelledError Exception would be swallowed by our code. This is not the case anymore so you should now trap that Exception yourself.
• Clean up the file upload interface with FileVar class (#549): The file upload functionality has been modified to require FileVar instances for uploaded files (the old method still works but is deprecated). See https://gql.readthedocs.io/en/latest/usage/file_upload.html
• Set logging level to DEBUG for all transports (#552)
• introspection now requests deprecated input fields by default (#553)
• Trapping dependencies Exceptions into TransportConnectionFailed (#558): Now gql will trap Exceptions raised by dependencies when executing a request and will encapsulate that Exception into the TransportConnectionFailed Exception
• Set ssl=True by default for AIOHTTPTransport (#538) (issue #529)
• New TransportConnectionClosed Exception replacing ConnectionClosed Exception (#536)
• websocket attribute removed from transport, now using _connected instead (#536)
• Upgrade lastest websockets and Exceptions overhaul (#543)

Features

Batching requests is now fully supported, on sync or async transports, with automatic batching:

• Implementation of execute_batch for async transports (#550)
• Implementation of automatic batching for async (#554)

See https://gql.readthedocs.io/en/latest/advanced/batching_requests.html

Fixes

• Fix httpx test deprecated warning (#542)
• Refactor websockets transports (#536) :

Refactor WebSockets Transport with Dependency Injection Architecture

This major architectural improvement implements dependency injection patterns across the WebSockets transport layer, creating a more modular, testable, and extensible system:

• Created abstract AdapterConnection interface in common/adapters/connection.py
• Implemented concrete WebSocketsAdapter to wrap the websockets library
• Moved websockets_base.py to common/base.py maintaining better structure which is independant of the websockets library used
