 * Upgraded Beam vendored Calcite to 1.40.0 for Beam SQL ([#35483](https://github.com/apache/beam/issues/35483)), which
   improves support for BigQuery and other SQL dialects. Note: Minor behavior changes are observed such as output
   significant digits related to casting.
+* (Python) The deterministic fallback coder for complex types like NamedTuple, Enum, and dataclasses now uses cloudpickle instead of dill. If your pipeline is affected, you may see a warning like: "Using fallback deterministic coder for type X...". You can revert to the previous behavior by using the pipeline option `--update_compatibility_version=2.67.0` ([35725](https://github.com/apache/beam/pull/35725)). Report any pickling related issues to [#34903](https://github.com/apache/beam/is [...]
 * (Python) Prism runner now enabled by default for most Python pipelines using the direct runner ([#34612](https://github.com/apache/beam/pull/34612)). This may break some tests, see https://github.com/apache/beam/pull/34612 for details on how to handle issues.
