+# array-api-strict Changelog
+
+## 1.0 (????)
+
+This is the first release of `array_api_strict`. It is extracted from
+`numpy.array_api`, which was included as an experimental submodule in NumPy
+versions prior to 2.0. Note that the commit history in this repository is
+extracted from the git history of numpy/array_api/ (see the [README](README.md)).
+
+Additionally, the following changes are new to `array_api_strict` from
+`numpy.array_api` in NumPy 1.26 (the last major NumPy release to include
+`numpy.array_api`):
+
+- ``array_api_strict`` was made more portable. In particular:
+
+  - ``array_api_strict`` no longer uses ``"cpu"`` as its "device", but rather a
+    separate ``CPU_DEVICE`` object (which is not accessible in the namespace).
+    This is because "cpu" is not part of the array API standard.
+
+  - ``array_api_strict`` now uses separate wrapped objects for dtypes.
+    Previously it reused the ``numpy`` dtype objects. This makes it clear
+    which behaviors on dtypes are part of the array API standard (effectively,
+    the standard only requires ``==`` on dtype objects).
+
+- ``numpy.array_api.nonzero`` now errors on zero-dimensional arrays, as
+    required by the array API standard.
+
+- Support for the optional [fft
+  extension](https://data-apis.org/array-api/latest/extensions/fourier_transform_functions.html)
+  was added.
