+## pydantic-zarr 0.9.1 (2025-12-12)
+
+### Features
+
+- Add `with_*` methods to the experimental `ArraySpec` and `GroupSpec` classes.
+  These methods make it easier to create copies of existing `ArraySpec` and `GroupSpec` objects with
+  new properties. ([#137](https://github.com/zarr-developers/pydantic-zarr/issues/137))
+
+### Bugfixes
+
+- Make V3 `ArraySpec` validation reject dimension names that don't match the dimensionality of the array. ([#136](https://github.com/zarr-developers/pydantic-zarr/issues/136))
+- Fix a bug that prevented creation of `experimental.v3.GroupSpec` instances with typed members. ([#138](https://github.com/zarr-developers/pydantic-zarr/issues/138))
+- Fix a bug where `experimental.v3.ArraySpec` instances took a default parameter for attributes. ([#138](https://github.com/zarr-developers/pydantic-zarr/issues/138))
