Highlights
Python 3.13 is officially supported
Python 3.13 is now officially supported and Python 3.8 is no longer supported.
Pydantic is officially supported
The SDK now contains a data converter that supports conversion of all types supported by Pydantic to and from JSON. In addition to Pydantic models, these include all json.dump-able types, various non-json.dump-able standard library types such as dataclasses, types from the datetime module, sets, UUID, etc, and custom types composed of any of these. Usage:
from temporalio.client import Client
from temporalio.contrib.pydantic import pydantic_data_converter
client = Client(data_converter=pydantic_data_converter, ...)This data converter supports Pydantic v2 only.
