+
+### Bug Fixes
+
+* **client:** close streams without requiring full consumption ([31e3903](https://github.com/writer/writer-python/commit/31e39034cab026c34c9509757a27d9e2221c0c5b))
+* compat with Python 3.14 ([56db271](https://github.com/writer/writer-python/commit/56db2716054e1ba6a23071e172584e7c2433ba87))
+* **compat:** update signatures of `model_dump` and `model_dump_json` for Pydantic v1 ([1fb3322](https://github.com/writer/writer-python/commit/1fb332284ab2c7ff87afeb686176df1efcf262db))
+* ensure streams are always closed ([23c7971](https://github.com/writer/writer-python/commit/23c7971d69301956cef01d0041120a848818fa5a))

+                exclude: A set of fields to exclude from the output.
+                context: Additional context to pass to the serializer.

-                exclude_defaults: Whether to exclude fields that are set to their default value from the output.
-                exclude_none: Whether to exclude fields that have a value of `None` from the output.
-                round_trip: Whether to enable serialization and deserialization round-trip support.
-                warnings: Whether to log warnings when invalid fields are encountered.

+                exclude_defaults: Whether to exclude fields that are set to their default value.
+                exclude_none: Whether to exclude fields that have a value of `None`.
+                exclude_computed_fields: Whether to exclude computed fields.
+                    While this can be useful for round-tripping, it is usually recommended to use the dedicated
