  async def greet_with_cm(ctx: Context, name: str) -> str:
      return my_resource_manager.value
  ```

  * Add `msgspec` support, works out of the box when adding `restate_sdk[serde]` dependency:

  ```python theme={null}
  # models
  class GreetingRequest(msgspec.Struct):
      name: str

  class Greeting(msgspec.Struct):
      message: str

  msgspec_greeter = Service("msgspec_greeter")

  @msgspec_greeter.handler()
  async def greet(ctx: Context, req: GreetingRequest) -> Greeting:
      return Greeting(message=f"Hello {req.name}!")
  ```

  * Add extension modules for Google ADK and OpenAI, more info soon!

  ### What's Changed

</Update>

<Update label="2025-11-18" description="Python SDK v0.12.0">
  ### New features :tada:

  * Added ingress client to send requests from your python applications to restate services:

  ```python theme={null}
  async with restate.create_client("http://localhost:8080") as client:
    await client.object_call(increment, key="a", arg=5)
    await client.object_send(increment, key="a", arg=5)

    current_count = await client.object_call(count, key="a", arg=None)
  ```

  * Added new test harness constructor to be used in combination with `@pytest.fixture`:

  ```python theme={null}
  # Your fixture
  @pytest.fixture(scope="session")
  async def restate_test_harness():
    app = restate.app([greeter])
    async with restate.create_test_harness(app) as harness:
          yield harness
          
  # A test example, using the client
  async def test_greeter(restate_test_harness: HarnessEnvironment):
      greeting = await restate_test_harness.client.service_call(greet, arg="Pippo")
      assert greeting == "Hello Pippo!"
  ```

  * Various type hints improvements, such as [https://github.com/restatedev/sdk-python/issues/112](https://github.com/restatedev/sdk-python/issues/112)

  ### What's Changed

  * Revert usage of asyncio cancellation mechanism by @slinkydeveloper in [https://github.com/restatedev/sdk-python/pull/142](https://github.com/restatedev/sdk-python/pull/142)
  * Update `crazy-max/ghaction-setup-docker` to v4 by @muhamadazmy in [https://github.com/restatedev/sdk-python/pull/144](https://github.com/restatedev/sdk-python/pull/144)

  [View on GitHub](https://github.com/restatedev/sdk-python/releases/tag/v0.12.0)
</Update>

<Update label="2025-10-21" description="Python SDK v0.11.0">
  ### New features

  * You can configure more retry options for `ctx.run_typed`:

  ```python theme={null}
  ctx.run_typed("payment", payment, RunOptions(
      # Initial retry interval
      initial_retry_interval=timedelta(milliseconds=100),
      # Retry policies are exponential, the retry interval will double on each attempt
      retry_interval_factor=2.0,
      # Maximum retry interval
      max_retry_interval=timedelta(seconds=10),
      # Max duration of retries before giving up
      max_duration=timedelta(minutes=5),
      # Max attempts (including the initial) before giving up
      max_attempts=10,
  ))
  ```

  * You can now provide a name to `sleep`, you'll be able to see this name in the UI.

  ### Notable changes

  * When [suspending](https://docs.restate.dev/foundations/key-concepts#suspensions-on-faas), the SDK will now throw an [`asyncio.CancelledError`](https://docs.python.org/3/library/asyncio-task.html#task-cancellation), instead of the previously thrown custom error. Catch this exception **only** if you need to cleanup some external resources between execution attempts.

  ### What's Changed

  * Use task cancellation instead of custom suspension exception by @slinkydeveloper in [https://github.com/restatedev/sdk-python/pull/132](https://github.com/restatedev/sdk-python/pull/132)

  * Fix ctx.time()  by @slinkydeveloper in [https://github.com/restatedev/sdk-python/pull/138](https://github.com/restatedev/sdk-python/pull/138)
  * Expose all run retry options by @slinkydeveloper in [https://github.com/restatedev/sdk-python/pull/137](https://github.com/restatedev/sdk-python/pull/137)
  * Test suite 3.2 upgrade by @slinkydeveloper in [https://github.com/restatedev/sdk-python/pull/139](https://github.com/restatedev/sdk-python/pull/139)
  * Use service image by @slinkydeveloper in [https://github.com/restatedev/sdk-python/pull/140](https://github.com/restatedev/sdk-python/pull/140)
  * Fix lint warning by @igalshilman in [https://github.com/restatedev/sdk-python/pull/141](https://github.com/restatedev/sdk-python/pull/141)
