+# 1.1 (2023-02-24)
+
+## Major Changes
+
+- Added support for PyTorch.
+
+- Add helper function `size()` (required if torch is used as
+  `torch.Tensor.size` is a method that is incompatible with the array API
+  [`.size`](https://data-apis.org/array-api/latest/API_specification/generated/array_api.array.size.html#array_api.array.size)).
+
+- All wrapper functions that wrap existing library functions now pass through
+  arbitrary `**kwargs`.
+
+## Minor Changes
+
+- Added CI to run against the [array API testsuite](https://github.com/data-apis/array-api-tests).
+
+- Fix `sort(stable=False)` and `argsort(stable=False)` with CuPy.
+
+# 1.0 (2022-12-05)
+
+## Major Changes
+
+- Initial release. Includes support for NumPy and CuPy.
