+v25.4.0
+-------
+
+* Add Extension(py_limited_api=True). When set to a truthy value,
+  that extension gets a filename apropriate for code using Py_LIMITED_API.
+  When used correctly this allows a single compiled extension to work on
+  all future versions of CPython 3.
+  The py_limited_api argument only controls the filename. To be
+  compatible with multiple versions of Python 3, the C extension
+  will also need to set -DPy_LIMITED_API=... and be modified to use
+  only the functions in the limited API.
