v2.0.0-beta7

Enhancements

• Breaking: Support Pydantic v2 and dropping support for v1 #588
• Breaking: The attempting to access an unset oneof now raises an AttributeError field. To see how to access oneof fields now, refer to #558 and README.md.
• Breaking: A custom Enum has been implemented to match the behaviour of being an open set. Any checks for isinstance(enum_member, enum.Enum) and issubclass(EnumSubclass, enum.Enum) will now return False. This change also has the side effect of preventing any passthrough of Enum members (i.e. Foo.RED.GREEN doesn't work any more). See #293 for more info, this fixed many bugs related to Enum handling.
• Add support for pickle methods #535
• Add support for Struct and Value types #551
• Add support for Rich package for pretty printing #508
• Improve support for streaming messages #518 #529
• Improve performance of serializing / de-serializing messages #545
• Improve the handling of message name collisions with typing by allowing the method / type of imports to be configured.
  Refer to #582 and README.md.
• Add a warning when calling a deprecated message #596

Bug Fixes

• Fix roundtrip parsing of datetimes #534
• Fix accessing unset optional fields #523
• Fix Message equality comparison #513
• Fix behaviour with long comment messages #532

v2.0.0-beta5

Enhancements

• Breaking: Client and Service Stubs no longer pack and unpack the input message fields as parameters #331:

  response = await service.echo(EchoRequest(value="hello", extra_times=1))

  Servers before:

  async def echo(self, value: str, extra_times: int) -> EchoResponse: ...

  Servers after:

  async def echo(self, echo_request: EchoRequest) -> EchoResponse:
      # Use echo_request.value
      # Use echo_request.extra_times
      ...
